누가 왜 쓰시는거죠...? 잘 작동하나요? 댓글로 남겨주시면 감사하겠습니다.

fintuned the kykim/bert-kor-base model as a dense passage retrieval context encoder by KLUE dataset this link is experiment result. https://wandb.ai/thingsu/DenseRetrieval

Corpus : Korean Wikipedia Corpus

Trained Strategy :

• Pretrained Model : kykim/bert-kor-base
• Inverse Cloze Task : 16 Epoch, by korquad v 1.0, KLUE MRC dataset
• In-batch Negatives : 12 Epoch, by KLUE MRC dataset, random sampling between Sparse Retrieval(TF-IDF) top 100 passage per each query

You must need to use Korean wikipedia corpus
