This is a sentence-transformers model finetuned from avsolatorio/GIST-small-Embedding-v0. 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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("moshew/gist_small_ft_gooaq_v1")
# Run inference
sentences = [
    'how long does it take to transfer money between anz and westpac?',

You can get the Mini Statement (by an SMS) for last 5 transactions in your account by giving a Missed Call to 18008431133. 1.",
    "Simply put, 1 ply toilet paper is made of a single layer of paper, while 2 ply has two layers. ... In the 1950's, a manufacturer created a method to roll and attach one-ply paper together to make a thicker “two-ply”. For years, 2-ply toilet tissue was always thicker and usually assumed to be better.",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
