slimaneMakh/triplet_CloseHlabel_farLabel_400K-5eps-distiluse-base-multilingual-cased-v2_10may

This is a sentence-transformers model: It maps sentences & paragraphs to a 512 dimensional dense vector space and can be used for tasks like clustering or semantic search.

It is trained on a dataset of 400K examples :

• Anchor: Label
• Positive : Human label
• Negative : also human label It is build as a positive pair (anchor, positive) and negative pair. The negative is sampled amongst closest human label from the positive sample with a different label.

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('slimaneMakh/triplet_CloseHlabel_farLabel_400K-5eps-distiluse-base-multilingual-cased-v2_10may')
embeddings = model.encode(sentences)
print(embeddings)
