TanhExp
Tanh Exponential Activation Function
Lightweight or mobile neural networks used for real-time computer vision tasks contain fewer parameters than normal
networks, which lead to a constrained performance. In this work, we proposed a novel activation function named Tanh Exponential
Activation Function (TanhExp) which can improve the performance for these networks on image classification task significantly.
The definition of TanhExp is $f(x) = x tanh(e^x)$. We demonstrate the simplicity, efficiency, and robustness of TanhExp on various
datasets and network models and TanhExp outperforms its counterparts in both convergence speed and accuracy. Its behaviour
also remains stable even with noise added and dataset altered. We show that without increasing the size of the network, the
capacity of lightweight neural networks can be enhanced by TanhExp with only a few training epochs and no extra parameters
added.
