+# xlm-roberta-base fine-tuned on custom cross‑encoder dataset
+
+This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [FacebookAI/xlm-roberta-base](https://huggingface.co/FacebookAI/xlm-roberta-base) on the [reranker_10k](https://huggingface.co/datasets/MercuraTech/reranker_10k) dataset 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("egerber1/xlm-roberta-crossencoder")
+# Get scores for pairs of texts
+pairs = [
+    ['Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren', 'Geberit PE Elektroschweißband für Fixpunkt DN70'],
+    ['Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren', 'Geberit Rohrschelle gedämmt Gewindemuffe M8/10 DN70'],
+    ['Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren', 'Geberit PE Steckmuffe mit Lippendichtung DN70'],
+    ['Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren', 'Geberit PE Elektroschweißband für Fixpunkt DN56'],
+    ['Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren', 'Geberit PE Elektroschweißband für Fixpunkt DN90'],
+]
+scores = model.predict(pairs)
+print(scores.shape)
+# (5,)
+
+# Or rank different texts based on similarity to a single text
+ranks = model.rank(
+    'Elektroschweißband für Fixpunkt DN 70 Elektroschweißband für Fixpunkt - Zur Fixpunktbefestigung von Rohren in Verbindung mit Rohrschellen - Einteilig - Nennweite: DN 70 liefern und montieren',
+    [
+        'Geberit PE Elektroschweißband für Fixpunkt DN70',
