SentenceTransformer based on intfloat/e5-large-v2

This is a sentence-transformers model finetuned from intfloat/e5-large-v2. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for retrieval.

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("ainativestudio/locomo-e5-large-finetuned")
# Run inference
sentences = [
    "When did Evan finish the painting that's hanging in the exhibit?",
    "[6:48 pm on 17 December, 2023] Evan: Yeah, trying something new and succeeding gives a great feeling of accomplishment. Give it a go, even if it's just a little thing. You'll be amazed!",
    '[7:52 pm on 7 August, 2023] Evan: Yep, Sam! Consistency and perseverance will get us far. Great chat!',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000, -0.9972, -0.9972],
#         [-0.9972,  1.0000,  1.0000],
#         [-0.9972,  1.0000,  1.0000]])
