This is a Cross Encoder model finetuned from cross-encoder/ms-marco-MiniLM-L6-v2 using the sentence-transformers 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:

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("ayushexel/reranker-ms-marco-MiniLM-L6-v2-gooaq-bce-500k")
# Get scores for pairs of texts
pairs = [
    ['what are the 50 state mottos?', '[\'Maine. "Dirigo" (\\u200bI direct)\', \'44. California. "\\u200bEureka" (I have found it) ... \', \'Arizona. "Ditat Deus" (\\u200bGod Enriches) ... \', \'Indiana. "The Crossroads of America" ... \', \'Alaska. "North to the Future" ... \', \'Utah. "Industry" ... \', \'Delaware. "Liberty and Independence" ... \', \'Maryland. "Fatti maschii, parole femine" (Manly deeds womanly words) ... \']'],
    ['what does it mean when you have white pee?', 'A milky quality to your urine is typically caused by your body sending an increase in white blood cells to fight an infection. When these white blood exit your body via your urine, the cells mix, and your urine appears cloudy.'],
    ['what does it mean when you have white pee?', 'White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light.'],
    ['what does it mean when you have white pee?', "['Lower abdominal pain.', 'Pain during urination.', 'Frequent urination.', 'Difficulty urinating or interrupted urine flow.', 'Blood in the urine.', 'Cloudy or abnormally dark-colored urine.']"],
    ['what does it mean when you have white pee?', 'Peeps. ... Peeps are marshmallows sold in the United States and Canada that are shaped into chicks, bunnies, and other animals.'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'what are the 50 state mottos?',
    [
        '[\'Maine. "Dirigo" (\\u200bI direct)\', \'44. California. "\\u200bEureka" (I have found it) ... \', \'Arizona. "Ditat Deus" (\\u200bGod Enriches) ... \', \'Indiana.
