This is a Cross Encoder model finetuned from EuroBERT/EuroBERT-210m using the sentence-transformers library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

Dataset

sentence-transformers/gooaq

Description

This dataset is a collection of question-answer pairs, collected from Google.

Fine-Tuning Details

The model was trained using 578,402 training samples from sentence-transformer.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

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("fjmgAI/rerank1-210M-EuroBERT", trust_remote_code=True)
# Get scores for pairs of texts
pairs = [

scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
