luiz-and-robert-thesis/mpnet-frozen-newtriplets-lr-2e-7-m-1-e-5
This is a sentence-transformers model: It maps sentences & paragraphs to a 768 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('luiz-and-robert-thesis/mpnet-frozen-newtriplets-lr-2e-7-m-1-e-5')
embeddings = model.encode(sentences)
print(embeddings)
