+# CrossEncoder based on BAAI/bge-reranker-base
+
+This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [BAAI/bge-reranker-base](https://huggingface.co/BAAI/bge-reranker-base) 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("foochun/bge-reranker-ft")
+# Get scores for pairs of texts
+pairs = [
+    ['zach toh zhen bing', 'zach toh zhen bing'],
+    ['zach yap bing sheng', 'yap bing sheng zach'],
+    ['carmen chia zhen meng', 'carmen zhen chia meng'],
+    ['carmen lau zhen bing', 'carmen zhen bing lau'],
+    ['ajith s/o sockalingam', 'sockalingam ajith'],
+]
+scores = model.predict(pairs)
+print(scores.shape)
+# (5,)
+
+# Or rank different texts based on similarity to a single text
+ranks = model.rank(
+    'zach toh zhen bing',
+    [
+        'zach toh zhen bing',
+        'yap bing sheng zach',
+        'carmen zhen chia meng',
+        'carmen zhen bing lau',
+        'sockalingam ajith',
+    ]
+)
+# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
