Mercity/memory-retrieval-minilm-l6-v2

SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2. It maps sentences & paragraphs to a 384-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("Mercity/memory-retrieval-minilm-l6-v2")
# Run inference
sentences = [
    'Provide the amortization schedule difference for CC1 under both prioritization schemas.',
    "Mark's primary long-term goal is to start his own small business within the next four years, requiring significant capital savings to begin operations.",
    "Last spring, Dr. Vasquez received high praise from the Dean for successfully transitioning her entire curriculum to align with a newly adopted, highly structured 'Systems Thinking Framework' mandated by the university board.",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000,  0.9104, -0.3007],
#         [ 0.9104,  1.0000, -0.2945],
#         [-0.3007, -0.2945,  1.0000]])
