mteb-pt/average_pt_nilc_glove_s1000

This is an adaptation of pre-trained Portuguese GloVe Word Embeddings to a sentence-transformers model.

The original pre-trained word embeddings can be found at: http://nilc.icmc.usp.br/nilc/index.php/repositorio-de-word-embeddings-do-nilc.

This model maps sentences & paragraphs to a 1000 dimensional dense vector space and can be used for tasks like clustering or semantic search.

Usage (Sentence-Transformers)

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

Then you can use the model like this:

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('mteb-pt/average_pt_nilc_glove_s1000')
embeddings = model.encode(sentences)
print(embeddings)
