SentenceTransformer based on Alibaba-NLP/gte-multilingual-base

This is a sentence-transformers model finetuned from Alibaba-NLP/gte-multilingual-base. It maps sentences & paragraphs to a 768-dimensional dense vector space and 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 SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'Alıştırma özeti: Grafikleri verilen üç farklı fonksiyonun bire bir ve örten olup olmadığını yatay doğru testi kullanarak belirleyiniz.',
    'Alıştırma özeti: Sembolik olarak tanımlanmış fonksiyonlardan oluşan bir ifadenin birim fonksiyon olduğu bilgisiyle, bu fonksiyonların katsayılarının toplamının bulunması istenmektedir.',
    'Alıştırma özeti: Bir ifadenin polinom belirtmesi için, ifadede yer alan bir parametrenin alabileceği değerler toplamının bulunması istenmektedir.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000,  0.9725, -0.7514],
#         [ 0.9725,  1.0000, -0.7248],
#         [-0.7514, -0.7248,  1.0000]])
