cross-encoder-testing / reranker-bert-tiny-gooaq-bce

BERT-tiny trained on GooAQ

This is a Cross Encoder model finetuned from prajjwal1/bert-tiny using the sentence-transformers 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.

This model was trained using train_script.py .

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.

from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("cross-encoder-testing/reranker-bert-tiny-gooaq-bce")
# Get scores for pairs of texts
pairs = [
