SentenceTransformer based on google/bert_uncased_L-2_H-128_A-2

This is a sentence-transformers model finetuned from google/bert_uncased_L-2_H-128_A-2. It maps sentences & paragraphs to a 128-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("swardiantara/bert-tiny-snli-k3-fixed-euclidean")
# Run inference
sentences = [
    'A couple play in the tide with their young son. [SEP] The family is on vacation.',
    'A woman with a panda hat and headphones is in front of a man outside in the snow. [SEP] The man is on the beach.',
    'Male standing in the roadway, he is wearing a light colored shirt and holding a backpack. [SEP] A male is watching his dogs play.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 128]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.9983, 0.9951],
#         [0.9983, 1.0000, 0.9962],
#         [0.9951, 0.9962, 1.0000]])
