Reranker MiniLM L6 H384 Uncased Gooaq 5 Epoch 1995000

🚀 CrossEncoder based on nreimers/MiniLM-L6-H384-uncased

This is a Cross Encoder model designed to compute scores for text pairs. These scores can be utilized for text reranking and semantic search. It's finetuned from nreimers/MiniLM-L6-H384-uncased using the sentence-transformers library.

🚀 Quick Start

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("ayushexel/reranker-MiniLM-L6-H384-uncased-gooaq-5-epoch-1995000")
# Get scores for pairs of texts
pairs = [
    ['when is the 2020 democratic presidential debate?', 'Major candidates The nomination will be made official at the 2020 Democratic National Convention, tentatively scheduled for August 17–20, 2020 in Milwaukee, Wisconsin.'],
    ['when is the 2020 democratic presidential debate?', 'Major candidates As of June 8, 2020, former Vice President Joe Biden became the presumptive presidential nominee by amassing enough delegates to secure the nomination.'],
    ['when is the 2020 democratic presidential debate?', 'On March 5, 2019, Bloomberg announced that he would not run for president in 2020; instead he encouraged the Democratic Party to "nominate a Democrat who will be in the strongest position to defeat Donald Trump".'],
    ['when is the 2020 democratic presidential debate?', 'The electoral map for the 2020 election, based on populations from the 2010 Census. The 2020 United States presidential election is scheduled for Tuesday, November 3, 2020. It will be the 59th quadrennial presidential election.'],
    ['when is the 2020 democratic presidential debate?', 'There were a total of 29 major Democratic candidates. Of these, 23 candidates participated in at least one debate. Only Joe Biden and Bernie Sanders participated in all the debates; Pete Buttigieg, Amy Klobuchar, and Elizabeth Warren participated in all but one debate.'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'when is the 2020 democratic presidential debate?',
    [
        'Major candidates The nomination will be made official at the 2020 Democratic National Convention, tentatively scheduled for August 17–20, 2020 in Milwaukee, Wisconsin.',
        'Major candidates As of June 8, 2020, former Vice President Joe Biden became the presumptive presidential nominee by amassing enough delegates to secure the nomination.',
        'On March 5, 2019, Bloomberg announced that he would not run for president in 2020; instead he encouraged the Democratic Party to "nominate a Democrat who will be in the strongest position to defeat Donald Trump".',
