FlagEmbedding
- Update Embedding Models `bge-*-v1.5`:
- alleviate the issue of the similarity distribution
- the new models can do retrieval tasks without instruction, but still recommend using instruction which can have a better performance.
- New Models `bge-reranker-*`: cross-encoders that can rerank the top-k retrieved results
- Specify using normalization in the configuration for sentence-transformers, thanks to [skirres](https://huggingface.co/skirres).
Now users have no need to set `normalize_embeddings=True` manually when using sentence-transformers.
C-MTEB
- Add two cross-lingual retrieval tasks: T2RerankingZh2En and T2RerankingEn2Zh.
