AdaMLLab/AraMix-HQ

AraMix family: AraMix (minhash and matched) | AraMix-domain-classified (with domain labels) | AraMix-HQ (model-filtered)

AraMix-HQ is a high-quality subset of AraMix-MinHash created using model-based quality scoring. We adapt the approach from FineWeb2-HQ but replace the XLM-Roberta encoder with mmBERT, which provides better Arabic language understanding. We release the model at AdaMLLab/mmBERT-Arabic-Quality-Classifier.

AraMix-HQ outperforms both AraMix-Matched and FineWeb2-HQ on Arabic FineTasks benchmarks.

Usage

from datasets import load_dataset

ds = load_dataset("AdaMLLab/AraMix-HQ")

Method

1. Start with AraMix-MinHash (178B tokens, 179M documents)
2. Score documents using mmBERT-based classifiers trained to identify structured, knowledge-rich content
3. Filter to retain high-scoring samples
