Abstract: We present a system that learns to follow navigational natural language directions. Where traditional models learn from linguistic annotation or word distributions, our approach is grounded in the world, learning by apprenticeship from routes through a map paired with English descriptions. Lacking an explicit alignment between the text and the reference path makes it difficult to determine what portions of the language describe which aspects of the route. We learn this correspondence with a reinforcement learning algorithm, using the deviation of the route we follow from the intended path as a reward signal. We demonstrate that our system successfully grounds the meaning of spatial terms like above and south into geometric properties of paths.


Scenario
The health care provider needs to find all the patients who had treated by a doctor Durenda. Doctor's informaion and reports are stored in the PMD documents in XML format.
Operation
The XMLEXISTS predicate checks for the condition specified and returns a boolean accordingly. The example on the right shows that XMLEXISTS returns 'true' if the doctor's given name is 'Durenda' and 'false' if otherwise.
Solution
Patients treated by doctor Durenda are returned.

Let $\Omega=\{0,1\}^{n}$ with $p_{\underline{\omega}}=2^{-n}$ for each $\underline{\omega}\in \Omega$. Define the events $A=\{\underline{\omega}{\; : \;} \omega_{1}=0\}$, $A=\{\underline{\omega}{\; : \;} \omega_{2}=0\}$ and $C=\{\underline{\omega}{\; : \;} \omega_{1}+\omega_{2}=0 \mbox{ or }2\}$. In words, we toss a fair coin $n$ times and $A$ denotes the event that the first toss is a tail, $B$ denotes the event that the second toss is a tail and $C$ denotes the event that out of the first two tosses are both heads or both tails. Then $\mathbf{P}(A)=\mathbf{P}(B)=\mathbf{P}(C)=\frac{1}{4}$. Further,
\[\begin{aligned}
\mathbf{P}(A\cap B)=\frac{1}{4}, \mathbf{P}(B\cap C)=\frac{1}{4}, P(A\cap C)=\frac{1}{4}, \mathbf{P}(A\cap B\cap C)=\frac{1}{4}.
\end{aligned}\]
Thus, $A,B,C$ are independent
pairwise, but not independent by our definition because $\mathbf{P}(A\cap B\cap C)\not= \frac{1}{8}=\mathbf{P}(A)\mathbf{P}(B)\mathbf{P}(C)$.
Intuitively this is right. Knowing $A$ does not given any information about $C$ (similarly with $A$ and $B$ or $B$ and $C$), but knowing $A$ and $B$ tells us completely whether or not $C$ occurred! Thus is is right that the definition should not declare them to be independent.


HOUSEGUEST (PG)
Directed by Randall Miller Running Time: 113 minutes Originally Released: January 6, 1995
Reviewed by E. Benjamin Kelsey
* * ½ (out of four)
Let's get one thing straight - I *loved* this film. Yeah, it's got some prime examples of shoddy film-making, but on the surface of all it's excessive cheeziness, it's really funny. It's one of those movies I embarrassingly liked so much, I would quickly recommend it, even if it's more worthy of a Razzie than an Oscar. With that out in the open, let me tell you why HOUSEGUEST, a hilarious film, is so bad.
HOUSEGUEST stars the one-name comedian Sinbad as Kevin Franklin, an orphan who grew up on the poor side of town with big dreams he never let go. Even as an adult, no matter how much people tell him to "get real", Kevin is determined to make something of himself. He cruises around in a laughably compact car playing out scenarios of famed acclamation like a young boy pretending to be a superhero. He looks for answers in lottery tickets and "get rich quick" infomercials, all the while keeping his meager lifestyle barely afloat thru organized crime connections, but when things begin to catch up with him, a $50,000 debt for example, Kevin finds himself needing to skip town.
At the airport on the verge of escape, two thugs (Paul Ben-Victor and Tony Longo) determined to collect the debt begin a chase after Kevin. When it seems he can go no further, Kevin overhears a family discussing the man they are supposed to be picking up. The father of the group, Gary Young ("SNL" alumnus and current co-star of "NewsRadio" Phil Hartman), explains that the man is an old friend whom he hasn't seen in decades. He's also black, and that's all it takes to convince Kevin to pose as someone he knows otherwise nothing about.
The Young's take Kevin into their posh suburban home, and thru overly silly comedic events, he discovers more and more about the man he has taken the identity of - renowned dentist Derek Bond (Ron Glass). But Kevin is quite different from Derek, and his laid-back, party-hearty attitude is quite a jolt to the otherwise serious-minded community he finds himself in. Seemingly uncouth at first, Kevin becomes more and more of a mentor and therapist to the unprioritized Gary, the confidence-lacking son Jason (Chauncey Leopardi), and the misunderstood/misguided daughter Brooke (Kim Murphy).
Kevin's true identity is constantly at risk of being revealed, but despite his deceitful actions, he has a heart of gold. The Young's charitable hospitality makes it even more difficult on Kevin, who develops a genuine fondness for the family - after all, they're the closest thing to a real family Kevin has ever known. But as we wait for Kevin to be painfully brought into the open, we are hit hard with cornball humor, and I must admit, I loved every minute of it. Thru intentionally campy acting and amateurish, hyper editing, I was easily entertained with the cinematic equivalent of cheese puffs. There wasn't a lot of substance, but it tasted good, and I enjoyed binging on all the brainlessness.
HOUSEGUEST suffers terribly from blatant incontinuities and cartoonish film- making, and I'm surprised the producing credits didn't go to McDonald's after the most obvious display of product placement movies have ever taken. But even though the whole film could be viewed as a two-hour commercial for Mickey D's, it would still be a funny enough commercial to make it worthwhile. The acting was campy, but surprisingly, the one who stood out like a sore thumb was the one who took his role the most seriously - Stan Shaw. As Kevin's best friend Larry, Shaw seems a bit too serious about the project, which in turn makes him hard to swallow. It doesn't demean him as an actor, but it does make him very off-balance from the rest of the cast. Serious performances should still be light in a film like this, and Kim Griest as Emily Young (the mom of the family) is the one who does it right.
>From a wholly artistic viewpoint, HOUSEGUEST probably doesn't even deserve two stars, but I laughed so much that I had to give it a recommendable grade. If you're looking for intelligent comedy, or even a half-decent film, this isn't really the way to go, but if you're looking for laughs, I think it's a great choice. It's really hard to predict how you'll feel about this film. Somehow it just rubbed me the right way, and I can't deny that even after seeing it a few times, I laugh when I see it again. Be forewarned, it's not for everyone, but at the same time, it resembles a good pizza: flimsy, cheap, and extra cheezy.

Adding a context menu to map objects
This example shows how to add a context menu for the map and map objects. Map has a default context items to show the click position, centring the map and creating a circle. Circles have their own context menu item to remove them.
In order to add context menu items, first you need to subscribe to contextmenu event. ContextMenuEvent has a special items property, where menu items are stored. Each menu item is an instance of H.util.ContextItem class.
By default new menu items does not replace the previous ones, instead all items are collected and displayed together. However you can easily modify the items array to change this behaviour.
Context items can be visually separated from each other by using the H.util.ContextItem.SEPARATOR.


Please add an option to hide a server that is on the radar, instead of showing it in red (use the 'hide' CSS property instead or whatever). Let those of us who prefer to have servers hidden have the ability to toggle this option.
If we wanted to remove a server from the radar, we can toggle the hide option off so it shows up in red again allowing us to right click it.

Already asked in the past. Rejected because this is not what we want to do, for several reasons.

What reasons?
At least, then, is there a way to write a mod/plugin that allows us to replace the red background CSS with a hide property instead?
When I radar/blacklist a server, I really do not want to see it any longer -- it being red just draws my eye to it and frustrates me.
By the way, right-clicking to add to radar does not work on the Favorites or History tabs -- only on the server browser tab, FYI. Using Firefox 26.0.

Everybody can make a plugin that do that.
The reasons are simple and different variations of that Problem: Much more and complex work to do that because this have many sideffects.
I don't want explain it more detailed because the point is, it will not be integrated in BBLog.
As another reason, BBLog do not completely hide things in Battlelog

This is a part of a big story.
The King App (representing software application controller¹) and a little girl (representing data model) were searching for a name for the girl.
They had travelled to a swamp filled with various reptiles.
Including the largest one — Array the Monster.
¹) Don't care about the terms :)
* * *
— We can't fight with the monster alone, — the King said.
— We must go back and find an army.
The girl wasn't happy about going back. She didn't expect to meet new friends without her own name. So she asked:
— Do we need the army?
— Сertainly!, — the King answered.
— We need fifty designers to fight with Array the Monster.
— Why fifty designers?
— For the best effect. Imagine how it feels when fifty men are running to you and screaming «I'll fix it!».
The girl imagined.
— May I go to fight with the monster without an army?, — the girl asked.
The King had no objections. There was a theoretical chance that a little girl would win a huge monster. But to use this chance we need to update the storyline with superpower or lucky tricks. So the King answered:
— No.  These lucky tricks in the storyline are boring.
— What if I grow up?, — the girl suggested.
— It sounds more interesting!, — the King answered.
The girl moved to the swamp coast. She closed her eyes and took a deep breath.
It was very interesting already. All reptiles from the swamp came closely to see. After a moment the reptiles made a loud noise with a lot of questions.
— Have You grown up already?
— How does it feel?
— Why do You look like the same?
— Can You say something smart?
... they had asked a lot of questions.
A young woman smiled and answered once for all the questions.
— Yes, I have grown up without a trick, — she said.
— I have replaced in the text the «little girl» for the «young woman».
I am more responsible now.
For all of You and for anything else in this story.
— One more question, please!, — said the biggest reptile.
He was Array the Monster. He moved slowly and joined the conference at that moment.
— How will you defeat me?, — the monster asked.
— Because I am as huge as an office building for a common insurance company.
Do You have any responsible solutions in this case?
— Fifty designers are our solution!, — battlecryed the King.
He took the sword and was ready to fight. But the young woman had answered first.
— I have the solution, — she said.
— Dear Monster, You will tell us about reptiles.
We will listen to your lection sharply.
I will take one little lizard as an award.
This lizard will represent my name.
Everyone agreed with the deal.

Direct Metal Laser Sintering of Inconel 718

Direct Metal
Laser Sintering (DMLS) is an additive manufacturing technology that NASA hopes
to utilize to produce complex J-2X engine parts made of Inconel 718, a
nickel-chromium super alloy. We performed a comprehensive series of tensile,
low and high cycle fatigue, fracture toughness, and fatigue crack growth tests
at temperatures ranging from -320°F to 1200°F. We will use this data to determine whether or not
DMLS Inconel 718 is an acceptable replacement for wrought Inconel 718 as a
material for parts in the J-2X Engine. Ultimately this study will help NASA
improve the strength, durability, and reliability of parts that currently
require strength-reducing welding processes to manufacture, while
simultaneously reducing cost of production.

irect Metal Laser Sintering (DMLS) is an additive manufacturing
technology that succeeds in producing metallic parts with properties very
similar to traditional wrought manufactured parts. NASA is interested in the
technology because DMLS parts can be “printed” without the need to join and
weld multiple pieces together. Welding is typically associated with a Heat
Affected Zone (HAZ), inside which material strength and other properties are
significantly compromised. Another recent technological innovation to avoid the
weakening effects of the heat affected zone is Friction Stir Welding (FSW).
Friction Stir Welding works well on large, straight, relatively flat surfaces,
but small geometrically complex parts must still be manufactured by some of the
more traditional joining techniques such as Tungsten Inert Gas (TIG) Welding or
Electron Beam Welding (EBW). Both TIG welding and EBW are accompanied by a heat
affected zone where material properties such as tensile and fatigue strength
are compromised due to increased likeliness of cracks and brittleness.
NASA builds rocket engines,
and most of the material in a rocket engine must not only withstand, but
continue operating nominally despite being exposed to extremely severe
environments. Over time, materials such as Inconel superalloys,
Aluminum-Lithium alloys, and carbon composites have been developed to meet the
stringent demands of Aerospace Engineering design, but regions around welds and
other stress concentrators are theoretically and historically prime candidate points
of origin for failure regardless of bulk material strength. Direct Metal Laser
Sintering, or Selective Laser Melting (SLM) as NASA calls it, essentially
eliminates the need to join by welding, and in doing so removes much of the
uncertainty and risk associated with the Heat Affected Zone (HAZ). Ultimately,
the hope is that DMLS is a process that can cut time and cost while enabling
the manufacture of stronger, more cohesive, more reliable parts.
There are already several
target applications for DMLS Inconel 718. A discharge U-duct in the J-2X engine
is required to combat combustion instabilities in the gas generator assembly.
This U-duct must be small with a tight turn for acoustical reasons, and
currently must be manufactured by the joining of three separate pieces together
due to the geometric requirements of the part. This is undesirable because
these welds are sources of weakness and are expensive to complete and test for
quality assurance. This makes the U-Duct a prime candidate for DMLS
manufacture. Additionally, ER50 at Marshall Space Flight Center is hoping to
use the capabilities of Laser Sintering to manufacture a hollow, near spherical
combustion chamber in one continuous Titanium-based piece for the third stage
of a Nano Satellite Launch system that could put small payloads into space. The
previous requirement to join multiple sections of the sphere together ruled out
the possibility of building a feasible rocket for such small payloads.
This study aims to
understand how DMLS build parameters impact material properties of the final
product. We aimed to answer questions such as: How does build orientation
(stacking in x, y, or z axis) impact material properties? What minimum surface
roughness can be achieved without post-processing of DMLS builds? How does
surface roughness impact the fatigue strength of DMLS products? How does the microstructure
of DMLS products compare to wrought Inconel 718? Ultimately, answering
these questions will help establish industry standards for DMLS manufactured
parts.
Inconel
718 is a material used widely in aerospace due to its excellent thermal and
strength properties while retaining a high degree of reliability in extreme
conditions. The Inconel 718 super alloy is composed primarily of Nickel,
Chromium, and Iron, with lesser amounts of Niobium, Molybdenum, Titanium, and
Vanadium. It retains strength properties through 1300ºF, and has excellent
resistance to oxidation and corrosion through 1800 ºF. Inconel 718 is a notoriously
difficult material to machine because it responds to traditional machining
techniques with rapid work hardening, which subsequently tends to damage
machining tools. [1]
One of the best methods used to
understand a material is to simply look at it. Before any testing on DMLS
Inconel 718 began, a microscopy study was performed to better understand the physical
reasons for why the material behaved the way it did.
Wrought Inconel 718 is
characterized by equiaxed grain structure, with grains that have roughly equal
diameters in every direction. There is no directional bias in the growth of
grains in traditional wrought Inconel 718. Most of the DMLS samples exhibited
elongated grain structure with sharp endpoints. This was a consequence of the
sintering process for sequential layers of Inconel 718 powder. While the
microscopy study revealed an inherent microstructural difference between DMLS
and wrought products, further study would be necessary to determine the
specific consequence of these elongated DMLS grains. For the purposes of this
study, the goal was to use determine a suitable heat treatment to recrystallize
the DMLS specimens in such a way to most closely match the grain structure
observed in traditional wrought Inconel 718.
Figure 4. Micrograph of one vendor that succeeded in
eliminating elongation of Laser Sintered Grains. What build parameters
produced such a microstructure?
Figure 5. Wrought Inconel 718 Micrograph. Note roughly equiaxed grains.
Initial
tensile results from as-built samples were sub-par, far less than strengths
seen in wrought Inconel. Even the samples provided by Vendor #2, the one that
succeeded in producing equiaxial grain structure similar to that of wrought
Inconel 718, were relatively weak. Study found that the vendors had
stress-relieved the samples at temps above ASTM standards. To correct this, all
samples were homogenized via a heat treatment at 2125°F. This freed
strengthening elements Niobium and Titanium, which were tied up in the
solidification process. After heat treatment, sample hardness increased 30% to
acceptable levels. Additionally, DMLS 718 microstructure looked very similar to
wrought microstructures on samples from all vendors. Grains were equiaxed, with
roughly equal diameters in all directions.
The DMLS J-2X Discharge U-Duct currently struggles to meet traditional
standards for surface smoothness. This
results from the build methodology. As each layer is added, a support lattice
must be utilized to prop up hovering sections. Where these supports are
removed, dimples are left behind on the surface (see left). Exterior surfaces
can be polished to meet smoothness standards, but tight interior regions cannot
be easily reached.
Surface
roughness is known to have a non-trivial effect on fatigue strength of wrought
materials. Roughness creates facial areas with a high stress gradient, which
serve as ideal points of origin for fracture, and subsequently premature
failure of the material. We requested DMLS builds with a maximum surface
roughness of 125µin, and none of the vendors succeeded in meeting this requirement.
Figure 9: 3D image of the surface of an as-built DMLS
sample. Granular
roughness is apparent. Note the raised circular red portions and the
depressed blue areas. These granular sources of roughness are the result of
individual powder grains that were not fully sintered during the DMLS
build. There will always be some inherent surface roughness after the laser
sintering build phase for this reason.
Figure 10. 3D image of an intentional ridge built into one
of the vendors’ Tensile samples. The
intention of the ridge is unknown to us, though we suspect it has a
strengthening effect. With DMLS manufacture, it is possible to add subtle
structural features such as this lengthwise-oriented ridge to fortify
structures. Tensile results showed minor improvements in tensile strength
in these samples, though whether or not this improvement can be attributed
to the ridge has yet to be confirmed.
Build matrixes were requested from each vendor to include samples to test Tensile Strength, Low Cycle Fatigue (LCF), High Cycle Fatigue (HCF), Fracture Toughness (J1C), Creep, and Fatigue Crack Growth Rate (FCGR). The requested samples were delivered while still attached to the build platform from each vendor, and were separated using a diamond wire saw. The samples were treated with the aforementioned heat treatment, and subsequently tested.
Tensile Testing was performed on a standard MTS
Tensile tester, outfitted with a suspended ATS tube furnace to fit over the
sample. Strain was measured with an extensometer for room temperature samples,
and a strain gauge with ceramic arms was used for the high temperature tests.
The tensile testing was performed at three temperatures: room temperature, 800°F, and 1200°F. Prior to running the
tensile tests, initial parameters were recorded for each sample including
specimen hardness, length end-to-end, diameter at the midpoint, and 1” gage
markings centered on the midpoint.
After initial measurements were taken, each specimen
was in turn loaded into the MTS tensile tester. An extensometer was centered on
the midpoint of each specimen to measure the elongation of the sample as the
applied tensile load was increased. For the high temperature tests
thermocouples were placed at the top and bottom of each sample. Once target
temperature was reached for both thermocouples, the specimen was soaked for a
minimum of 15 minutes to ensure that the target temperature had time to
propagate through the sample. A difference of 80°F between the specimen top
and bottom was determined to be the limit for an acceptable temperature
gradient, since heat tended to accumulate at the top of the furnace. Tensile
tests were then performed, and after failure was reached final measurements
were recorded.
Tensile testing provided
information on the Modulus of Elasticity of DMLS Inconel 718, as well as the
0.2% Yield Strength, Ultimate Yield Strength, Elongation, and associated
reduction in area at the location of failure. Each characteristic was compared
to ASTM values for wrought Inconel 718. After initial tensile test results were
shown to be below par, the heat treatment brought tensile strengths and modulus
of elasticity up to levels more competitive with wrought Inconel 718. The
results of tensile testing at various temperatures are as follows:
Figure 13. Pre- Heat Treatment Tensile Results of DMLS
tensile samples. Tensile
results show a yield approximately 30% lower than expected for traditional
wrought Inconel 718, which has a 0.2% Yield around 150 KSI. [2] These
subpar results initiated the investigation into how grain structure affects
strength properties. After heat treatment issues were resolved, sample
hardness and tensile strengths improved, seen in subsequent tensile
results. Figure 14. Tensile Tests of DMLS Inconel 718 samples at
Room Temperature (RT). Results
show vastly improved tensile strengths after samples subjected to heat
treatment. These tensile strength meet the expected values for wrought
Inconel 718. Figure 15. Tensile Tests of DMLS Inconel 718 at 800°F.
Serrations in the
Stress-Strain curve post yielding can be attributed to Dynamic Strain Aging
(DSA) of the material within a certain temperature regime, and has been
observed in other Inconel Alloys. The work-hardening mechanism is a result
of the pinning of lattice dislocations due to the diffusion of solute
elements into the matrix of the material. To further confirm that DSA is an
inherent material property and not unique to DMLS samples, additional tests
of wrought Inconel 718 were performed at 800°F. After serrated results were
observed, testing of DMLS samples resumed. [3] Figure 16. Tensile Tests of DMLS Inconel 718 at 1200°F.
Note the reduction in Tensile
Strength at 1200ºF and reduction in elongation (strain) before failure.
The results of the tensile
testing on DMLS Inconel 718 were comparable to values seen in wrought Inconel
718 with regards to Modulus of Elasticity, 0.2% Yield Strength, and Ultimate
Tensile Strength. These results suggest that once an appropriate post-build
heat treatment is applied to DMLs products, tensile strength is competitive
with strengths seen in wrought material.
While Fatigue testing we aimed to
understand the source of decreased performance in fatigue strength. Is it attributed
to surface roughness, or is fatigue strength of DMLS Inconel 718 suppressed
relative to wrought Inconel 718 regardless of surface roughness? This would
suggest that fatigue life is inherently a consequence of the DMLS manufacturing
process, and less attributable to some necessary post-processing such as
polishing.
To
understand the effect of roughness on material strength, we performed High
Cycle Fatigue (HCF) Tests. The MTS Tensile Tester was programmed to cycle at
40Hz between an upper and lower boundary tensile stress loading. Stress loads
ranging between 35% to 75% of Yield Strength were tested to establish a fatigue
curve with good statistical confidence. HCF tests were performed at room
temperature, 800°F, 1000°F, and 1200°F.
B. Results
Thus
far, only as-built samples have been tested. The above plot shows a noted
decrease in fatigue life, as is expected with any sample with a relatively
rough surface. At the moment there is little analysis to be made here, other
than making a statement that fatigue strength is markedly decreased, by about
30%, with rough DMLS surfaces. The consequence of this reduced fatigue
performance in DMLs Inconel 718 is that surfaces affected by the structural
lattice supports required to build 3D objects will suffer some decrease in
fatigue strength. The real analysis will come when these as-built samples are
compared to the performance of polished samples.
This
study shows that Direct Metal Laser Sintering Technology has made substantial
progress towards replicating the bulk material characteristics of traditionally
manufactured Inconel 718. However, elements such as surface roughness, heat
treatment, structural build features, and parts with particularly tight
tolerance requirements still present hurdles to overcome before DMLS will be
become a comprehensively superior manufacturing method. DMLS does succeed in significantly reducing the
cost of manufacturing parts with complex geometries.
In the
near-term, DMLS of Inconel 718 shows promise for a variety of NASA
applications, especially in the J-2X engine. It is currently at a Manufacturing
Readiness Level (MRL) 6, and material specifications must be fully established
before progressing to MRL-7. This project has identified final DMLS build
specifications such as heat treatment through microscopy studies, and hopes to
define surface roughness tolerances to assist this MRL transition.
This
study will continue after my departure, and will include comprehensive testing
of DMLS Inconel 718 including Creep, Fracture Toughness (J1C), Low Cycle
Fatigue (LCF), and Fatigue Crack Growth Rate (FCGR). As the testing moves
forward, a new set of questions should be addressed. What differences in build
parameters did Vendor #2 utilize to eliminate the grain boundary issues
observed in the other two vendors? When
Marshall Space Flight Center receives its DMLS machine, what DMLS build
parameters should be used to duplicate industry success? How much
microstructural difference should be tolerated in regards to Quality Control of
DMLS builds?

In PLEASANTVILLE U.S.A., it's always 72 degrees and sunny. Every house has a white picket fence, and a mom at home who has dinner on the table at 6:00 sharp. The hometown high school basketball team has never lost a game -- in fact, it has never missed a basket. Teenage lovebirds never go any farther than holding hands, and only then after they've been "pinned." The world and its values are completely black-and-white -- particularly white in the case of the population demographics. In PLEASANTVILLE everything is always perfect, it's always 1958, and nothing ever changes.
The one minor problem with Pleasantville is that it doesn't exist, nor has it ever existed. It's the world of an innocuous 1950s family sit-com, played in perpetual reruns on a cable nostalgia network. That doesn't prevent it from being extremely attractive to David (Tobey Maguire), a high school senior living in a single-parent home and a 1990s world of AIDS, economic uncertainty and warnings of impending environmental collapse. For David, Pleasantville is an escape, but he never expects to be physically transported, along with his wild-child twin sister Jennifer (Reese Witherspoon), into the world of the sit-com itself. There they take on the roles of Bud and Mary Sue, the wholesome offspring of wholesome parents George (William H. Macy) and Betty (Joan Allen) in a wholesome town where the road comes right back to where you started.
It's a great high-concept premise which could have worked strictly as a fish-out-of-water comedy. Jennifer is overwhelmed by the massive breakfast prepared by Betty, complete with ham steak and drenched in syrup; the basketball team captain responds with blank stares to Jennifer's sexual advances; the local fire department exists solely to rescue cats from trees. While Jennifer does her best to turn Pleasantville upside-down with her contemporary ways, David does his best to minimize the damage and preserve the simple world he has come to love. Screenwriter Gary Ross (BIG, DAVE) continues to show a flair for high concepts with a human touch in his directorial debut, generating laughs from the clash of Eisenhower-era and Clinton-era mores, as well as from characters awakening to the fact that seeking fulfillment may mean an end to their static bliss.
But PLEASANTVILLE isn't merely a whimsical lark. As he exposes his characters to experiences they'd never even considered, Ross turns the film into a pointed examination of what we really mean when we talk about "traditional family values." The sudden emergence of teenage rebellion and nascent feminism send townspeople into a panicked search for any way to ensure stability, driven by Pleasantville mayor Big Bob (the late J. T. Walsh, playing a marvelous amalgam of conservative platitude-spitters). PLEASANTVILLE digs into the barely-concealed anxiety and xenophobia at the heart of so much political retro-think, yet that's not even the film's most daring idea. Ross has the guts to take on the notion of original sin itself, suggesting that the very passion and curiosity which lead to upheaval in paradise are also what make us most alive and most human, giving color to an otherwise monochromatic existence.
It's unfortunate that Ross gets a bit too self-congratulatory about his social satire, particularly in the final half-hour. As tensions build in Pleasantville, the battle becomes a clash between those characters still in black-and-white and those whose new, life-changing experiences have left them "colored" -- and that may be the _least_ consistently underlined point. Ross starts repeating himself, weighing down the previously light tone and drifting away from solid dramatic anchors like Joan Allen's housewife on a journey of self-discovery. PLEASANTVILLE is a funny and thoughtful film, the kind that works best before it starts tattooing The Moral of the Story across your backbrain. It's plenty entertaining just watching the mythology of the "good old days" laid bare, exposed as a comforting fiction far removed from a world where coping with change is more productive than demonizing it.

- variable evaluation: pi
- function evaluation: sin(0)
- variable definition: a=3.5
- function definition: f(x)=x^2-1
- parentheses: (1-x)^2
To enter an expression cointaining letters, such as sin(x), use the ⇳ key on the basic keypad. It toggles opened/closed the letter keypad.

Operators
- + - × ÷ basic arithmetic
- ^ power
- % percent
- ! factorial
- # modulo
- √ square root
- ' first derivative
Tips
- Parentheses: you may omit the leading or final parentheses, e.g. 1+2)(3+4 is valid.
- Multiplication: you may omit the multiplication operator when unambiguous, e.g. 3π+2(1+2)
- Expression continuation: starting a new expression with an operator auto-inserts ans,
the result of the last expression.
- Clear: use the Enter key to quickly erase the whole input line.
- Scientific e notation: 1e3 is 1000.
- Angles in degrees instead of radians: use either sind(90) or sin(90deg).
- Use trackball Up/Down to navigate the history.
Derivative
It is possible to compute the first derivative of a function with one argument
using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function,
and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function:
E.g. f(x)=x^3+x^2+1, followed by f'(x).
Multi plot
To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";".
E.g. x;x^2;2
Binary, octal, hexadecimal
You can enter values in binary, octal or hexadecimal by prefixing them with 0b, 0o or 0x respectivelly, such as:
- binary: 0b1010
- octal: 0o17
- hexa: 0x100
Right now it is not possible to do the reverse operation, i.e. display a result in a non-decimal base.

Paralytics¶
Documentation: https://mrtovsky.github.io/Paralytics/.
Repository: https://github.com/mrtovsky/Paralytics/.
What is it?¶
Paralytics package was created in order to simplify and accelerate repetitive tasks during modeling and predictive analysis. It especially puts stronger emphasis on data preprocessing, which is often the most arduous stage of modeling.
The purpose of this package is to reduce to a minimum time allocated on repetitive activities preceding the problem-specific approach to a given problem, containing among others optimization of the applied machine learning techniques, which is the part that most of Data Scientists would like to devote the most energy to, however, by poorly prepared data, it is often only a fraction of the total work time devoted to the project.
Main Features¶
Highlighting the main functionalities of the Paralytics:
Expanded target encoding of categorical variables using double cross-validation technique with additional regularisation preventing favoritism of sparse categories with reduction of excessive adjustment to the training set, effectively reducing overfitting.
Discretization of continuous variables to ordinal using shallow decision tree or method based on Spearman’s rank-order correlation.
Processing data read into the DataFrames, including:
automatic unification of variable types,
grouping of sparse categories,
projecting of text variables whose unique elements symbolize a binary response onto binary variables,
imputation of missing data.
Collinearity reduction using such factors as: variance inflation factor (VIF) or correlation.
Installation¶
Dependencies¶
Paralytics package requirements are checked and, if needed, installed during the installation process automatically. Mainly used packages across the Paralytics are:
NumPy (>= 1.15.4)
Pandas (>= 0.23.4)
scikit-learn (>= 0.20.1)
SciPy (>= 1.1.0)
For visualizations:
matplotlib (>= 3.0.2)
The easiest way to install the package is using pip
:
pip install paralytics
If you want to omit the packages upgrade (when your version does not meet the requirements) run:
pip install paralytics --no-deps
When functionalities requiring optional dependencies are needed you can install those extra requirements by running:
pip install paralytics[<extra-name>]
For example, to use BaseSeleniumBrowser
(requires selenium) and VIFSelector
(requires statsmodels) run:
pip install paralytics[browser,vif]
Installation of all extras is possible via:
pip install paralytics[all]
You can always install directly from the github repository:
pip install git+https://github.com/mrtovsky/Paralytics.git

Version 0.1 - November 17, 2011
This is an initial draft of an online textbook for computational, corpus, quantitative and theoretical linguists, who want to make use of Python 3 for their educational, research and applied projects.
The material presented here was developed over the last years from course material and code generated for research purposes. It was initially created for Python 1.x, then adapted to Python 2.x, and finally here made available for Python 3.x.
Currently, all sections and the included code are under active development.

Now let's try to do some simple input and output to the predefined streams. The iostreams facility defines shift operators for formatted stream input and output. The output operator is the shift operator operator<<(), also called the inserter:
std::cout << "result: " << x << '\n';
Input is done through another shift operator operator>>(), often referred to as the extractor:
std::cin >> x >> y;
Both operators are overloaded for all built-in types in C++, as well as for some of the types defined in the C++ Standard Library; for example, there are inserters and extractors for bool, char, int, long, float, double, string, etc. When you insert or extract a value to or from a stream, the C++ function overload resolution chooses the correct extractor operator, based on the value's type. This is what makes C++ iostreams type-safe and preferable to C stdio (see Chapter 27).
It is possible to print several units in one expression. For example:
std::cout << "result: " << x;
is equivalent to:
std::operator<<(std::cout,"result: ").operator<<(x);
This is possible because each shift operator returns a reference to the respective stream. Almost all shift operators for built-in types are member functions of their respective stream class. (The shift operators for the character types, such as char and wchar_t, are an exception to this rule; they are namespace-scope functions in the C++ Standard Library namespace ::std.) These operators are defined according to the following patterns:
template<class charT, class traits> basic_istream<charT, traits>& basic_istream<charT, traits>::operator>>(type& x) { // read x return *this; }
and:
template<class charT, class traits> basic_ostream<charT, traits>& basic_ostream<charT, traits>::operator<<(type x) { // write x return *this; }
The notable exceptions are extractors and inserters for character types and pointers to such, which are defined as non-members.
Simple input and output of units as shown above is useful, yet not sufficient in many cases. For example, you may want to vary the way output is formatted, or input is parsed. Iostreams allow you to control the formatting features of its input and output operators in many ways. With the standard iostreams, you can specify:
The width of an output field and the adjustment of the output within this field
The precision and format of floating point numbers, and whether or not the decimal point should always be included
Whether you want to skip white spaces when reading from an input stream
Whether integral values are displayed in decimal, octal or hexadecimal format
and many other formatting options.
There are two mechanisms that have an impact on formatting:
Formatting control through a stream's format state
Localization through a stream's locale
The stream's format state is the main means of format control, as we demonstrate in the next section.

Mapping Geo Data¶
Bokeh has started adding support for working with Geographical data. There are a number of powerful features already available, but we still have more to add. Please tell use your use cases through the mailing list or on github so that we can continue to build out these features to meet your needs.
GeoJSON Datasource¶
GeoJSON is a popular open standard for representing geographical features with JSON. It describes points, lines and polygons (called Patches in Bokeh) as a collection of features. Each feature can also have a set of properties.
Bokeh’s GeoJSONDataSource
can be used almost seamlessly in place of Bokeh’s
ColumnDataSource
. For example:
from bokeh.io import output_file, show
from bokeh.models import GeoJSONDataSource
from bokeh.plotting import figure
from bokeh.sampledata.sample_geojson import geojson
geo_source = GeoJSONDataSource(geojson=geojson)
p = figure()
p.circle(x='x', y='y', alpha=0.9, source=geo_source)
output_file("geojson.html")
show(p)
The important thing to know is that behind the scenes, Bokeh converts the GeoJSON coordinates into columns called x and y (z where appropriate) or xs and ys depending on whether the features are Points, Lines, MultiLines, Polygons or MultiPolygons. Properties with clashing names will be overridden when the GeoJSON is converted, so the following code would not behave as expected.
Warning
If your GeoJSON properties contain a property x and you want to use this to set the size of your circles, and you do this:
Antipattern this will not work.
p.circle(size='x', alpha=0.9, source=geo_source)
You will not get the plot you expect because this is equivalent to
p.circle(x='x', y='y', size='x', alpha=0.9, source=geo_source)
and the x value from your properties will be overridden with the longitude values from your geometry coordinates.
Google Maps support¶
With the GMapPlot, you can plot any bokeh glyphs over a Google Map.
from bokeh.io import output_file, show
from bokeh.models import (
GMapPlot, GMapOptions, ColumnDataSource, Circle, Range1d, PanTool, WheelZoomTool, BoxSelectTool
)
map_options = GMapOptions(lat=30.29, lng=-97.73, map_type="roadmap", zoom=11)
plot = GMapPlot(x_range=Range1d(), y_range=Range1d(), map_options=map_options)
plot.title.text = "Austin"
# For GMaps to function, Google requires you obtain and enable an API key:
#
# https://developers.google.com/maps/documentation/javascript/get-api-key
#
# Replace the value below with your personal API key:
plot.api_key = "GOOGLE_API_KEY"
source = ColumnDataSource(
data=dict(
lat=[30.29, 30.20, 30.29],
lon=[-97.70, -97.74, -97.78],
)
)
circle = Circle(x="lon", y="lat", size=15, fill_color="blue", fill_alpha=0.8, line_color=None)
plot.add_glyph(source, circle)
plot.add_tools(PanTool(), WheelZoomTool(), BoxSelectTool())
output_file("gmap_plot.html")
show(plot)
Warning
There is an open issue documenting points appearing to be ~10px off from their intended location.
Google has its own terms of service for using Google Maps API and any use of Bokeh with Google Maps must be within Google’s Terms of Service
Tile Providers¶
Bokeh plots can also consume XYZ tile services which use the Web Mercator projection. The module bokeh.tile_providers
contains several pre-configured tile sources with appropriate attribution which can be added to a plot using the .add_tile() method.
from bokeh.io import output_file, show
from bokeh.plotting import figure
from bokeh.tile_providers import STAMEN_TONER
bound = 20000000 # meters
fig = figure(tools='pan, wheel_zoom', x_range=(-bound, bound), y_range=(-bound, bound))
fig.axis.visible = False
fig.add_tile(STAMEN_TONER)
output_file("stamen_toner_plot.html")
show(fig)
