+# CrossEncoder based on distilbert/distilroberta-base
+
+This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [distilbert/distilroberta-base](https://huggingface.co/distilbert/distilroberta-base) on the [all-nli](https://huggingface.co/datasets/sentence-transformers/all-nli) dataset using the [sentence-transformers](https://www.SBERT.net) library. It computes scores for pairs of texts, which can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

+## 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("tomaarsen/reranker-distilroberta-base-nli")
+# Get scores for pairs...
+pairs = [
+    ['Two women are embracing while holding to go packages.', 'The sisters are hugging goodbye while holding to go packages after just eating lunch.'],
+    ['Two women are embracing while holding to go packages.', 'Two woman are holding packages.'],
+    ['Two women are embracing while holding to go packages.', 'The men are fighting outside a deli.'],
+    ['Two young children in blue jerseys, one with the number 9 and one with the number 2 are standing on wooden steps in a bathroom and washing their hands in a sink.', 'Two kids in numbered jerseys wash their hands.'],
+    ['Two young children in blue jerseys, one with the number 9 and one with the number 2 are standing on wooden steps in a bathroom and washing their hands in a sink.', 'Two kids at a ballgame wash their hands.'],
+]
+scores = model.predict(pairs)
+print(scores.shape)
+# [5]
+
+# ... or rank different texts based on similarity to a single text
+ranks = model.rank(
+    'Two women are embracing while holding to go packages.',
+    [
+        'The sisters are hugging goodbye while holding to go packages after just eating lunch.',
+        'Two woman are holding packages.',
+        'The men are fighting outside a deli.',
+        'Two kids in numbered jerseys wash their hands.',
+        'Two kids at a ballgame wash their hands.',
+    ]
+)
+# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
