| # CrossEncoder based on BAAI/bge-reranker-v2-m3 |
|
|
| This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [BAAI/bge-reranker-v2-m3](https://huggingface.co/BAAI/bge-reranker-v2-m3) using the [sentence-transformers](https://www.SBERT.net) library. It computes scores for pairs of texts, which can be used for text reranking and semantic search. |

| ## Usage |
|
|
| ### Direct Usage (Sentence Transformers) |
|
|
| First install the Sentence Transformers library: |
|
|
| ```bash |
| pip install -U sentence-transformers |
| ``` |
|
|
| Then you can load this model and run inference. |
| ```python |
| from sentence_transformers import CrossEncoder |
| |
| # Download from the 🤗 Hub |
| model = CrossEncoder("cross_encoder_model_id") |
| # Get scores for pairs of texts |
| pairs = [ |
| ['A Hydro Flask in a light brown color with a small hand logo.', 'A large, light-brown Hydro Flask water bottle with a darker tan cap and black accents, appears to be made of metal, and seems to be in new condition with tags still attached.'], |
| ['A black smartphone.', 'The image shows four used smartphones, including a white and black Samsung smartphone, a black and silver phone of unknown brand, a white and black Nokia phone, and a white Apple iPhone, all appearing to be between 4 and 5 inches in screen size.'], |
| ['A purple pencil case with a unicorn design.', 'A new, mint green hard-shell pencil case with a ribbed texture and a central circular illustration of a unicorn with a rainbow mane.'], |
| ['A folded, dark blue umbrella has a slightly crinkled matching fabric case and its handle is still wrapped in clear plastic.', 'There are two blue umbrellas.'], |
| ['a black messenger bag with purple stitching.', 'A gray-green backpack with black mesh padding and an orange "NANEU PRO" tag on the side.'], |
| ] |
| scores = model.predict(pairs) |
| print(scores.shape) |
| # (5,) |
| |
| # Or rank different texts based on similarity to a single text |
| ranks = model.rank( |
| 'A Hydro Flask in a light brown color with a small hand logo.', |
| [ |
| 'A large, light-brown Hydro Flask water bottle with a darker tan cap and black accents, appears to be made of metal, and seems to be in new condition with tags still attached.', |
| 'The image shows four used smartphones, including a white and black Samsung smartphone, a black and silver phone of unknown brand, a white and black Nokia phone, and a white Apple iPhone, all appearing to be between 4 and 5 inches in screen size.', |
| 'A new, mint green hard-shell pencil case with a ribbed texture and a central circular illustration of a unicorn with a rainbow mane.', |
| 'There are two blue umbrellas.', |
| 'A gray-green backpack with black mesh padding and an orange "NANEU PRO" tag on the side.', |
| ] |
| ) |
| # [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...] |
