tomaarsen/reranker-NeoBERT-gooaq-bce

NeoBERT-medium trained on GooAQ

This is a Cross Encoder model trained 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.

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("tomaarsen/reranker-NeoBERT-gooaq-bce")
# Get scores for pairs of texts
pairs = [
    ['what are the signs of a bad yeast infection?', "['Itching and irritation in the vagina and vulva.', 'A burning sensation, especially during intercourse or while urinating.', 'Redness and swelling of the vulva.', 'Vaginal pain and soreness.', 'Vaginal rash.', 'Thick, white, odor-free vaginal discharge with a cottage cheese appearance.', 'Watery vaginal discharge.']"],
    ['what are the signs of a bad yeast infection?', 'Vaginal yeast infections can cause: itching and irritation in the vagina. redness, swelling, or itching of the vulva (the folds of skin outside the vagina) a thick, white discharge that can look like cottage cheese and is usually odorless, although it might smell like bread or yeast.'],
    ['what are the signs of a bad yeast infection?', 'It can feel like itching or maybe even burning. Or you may experience swelling so extreme, it leads to sores. Whether your symptoms are mild or severe, a yeast infection can be uncomfortable. Also known as vaginal candidiasis, yeast infections are caused by a fungus.'],
    ['what are the signs of a bad yeast infection?', 'Complications of untreated yeast infections If left untreated, vaginal candidiasis will most likely get worse, causing itching, redness, and inflammation in the area surrounding your vagina. This may lead to a skin infection if the inflamed area becomes cracked, or if continual scratching creates open or raw areas.'],
    ['what are the signs of a bad yeast infection?', "Drinking alcohol may also put you at greater risk for yeast infections. So if you're worried about yeast infection symptoms, consider curbing your cocktails. Eating only yeast-free foods is one way some women try to control yeast infections."],
]
scores = model.predict(pairs)
print(scores.shape)

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