+# FineWeb2-HQ-PlusPlus-Classifier
+
+This repository contains the model weights of the trained deep learning quality classifiers distilled from [FineWeb-edu](https://huggingface.co/HuggingFaceFW/fineweb-edu-classifier) and [DCLM](https://huggingface.co/mlfoundations/fasttext-oh-eli5) for multilingual text quality scoring. The classifier uses [jhu-clsp/mmBERT-base](https://huggingface.co/jhu-clsp/mmBERT-base) embeddings to score the documents and supports English and additional 100 languages.
+
+For more details, see our paper [Adapting English Quality Classifiers for Multilingual LLM Pretraining Data Selection](https://arxiv.org/abs/2610.11585).
+
+## Quickstart
+
+Classifier uses a simple architecture that takes mean-pooled mmBERT-base embeddings as input. For the DCLM-based classifier, softmax should be applied on the output logit, whereas for the FineWeb-edu-based classifier, the raw logit score should be used.
