한국어 임베딩의 한계와 qwen2.5 32b 모델의 평가 한계로 성능이 낮은 것으로 보입니다. 3 이상과 미만으로 구분할 때 f1 score는 약 0.59입니다.

devngho/ko_edu_classifier_v2_lemon-mint_LaBSE-EnKo-Nano-Preview-v0.3

This model is lemon-mint/LaBSE-EnKo-Nano-Preview-v0.3 with classfier head. It is designed to evaluate the educational value of Korean web pages, similar to the HuggingFaceFW/fineweb-edu-classifier, but focused on Korean content. The training data comes from devngho/ko_llm_annotations dataset, contains 500k samples extracted from blueapple8259/c4-ko-cleaned-2 and evaluated using Qwen/Qwen2.5-32B-Instruct.

The low performance is likely due to the limitations of Korean embeddings and the evaluation limitations of the Qwen2.5 32B model. The F1 score is about 0.59 when separating above and below 3.
