Redis semantic caching CrossEncoder model fine-tuned on Quora Question Pairs

This is a Cross Encoder model finetuned from cross-encoder/ms-marco-MiniLM-L6-v2 on the Quora Question Pairs LangCache Train Set dataset using the sentence-transformers library. It computes scores for pairs of texts, which can be used for sentence pair classification.

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("aditeyabaral-redis/langcache-crossencoder-v1-ms-marco-MiniLM-L6-v2")
# Get scores for pairs of texts
pairs = [
    ['How can I get a list of my Gmail accounts?', 'How can I find all my old Gmail accounts?'],
    ['How can I stop Quora from modifying and editing other people’s questions on Quora?', 'Can I prevent a Quora user from editing my question on Quora?'],
    ['How much does it cost to design a logo in india?', 'How much does it cost to design a logo?'],
    ['What is screenedrenters.com?', 'What is allmyapps.com?'],
    ['What are the best colleges for an MBA in Australia?', 'What are the top MBA schools in Australia?'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'How can I get a list of my Gmail accounts?',
    [
        'How can I find all my old Gmail accounts?',
        'Can I prevent a Quora user from editing my question on Quora?',
        'How much does it cost to design a logo?',
        'What is allmyapps.com?',
        'What are the top MBA schools in Australia?',
    ]
)
# [{'corpus_id': ..., 'score': ...}, {'corpus_id': ..., 'score': ...}, ...]
