SentenceTransformer based on seregadgl/spladegemmagooglebasecheckpoint100clear

This is a sentence-transformers model finetuned from seregadgl/splade_gemma_google_base_checkpoint_100_clear on the car_and_product_triplet_103k dataset. It maps sentences & paragraphs to a 768-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("seregadgl/splade_gemma_google_base_checkpoint_100_ver2")
# Run inference
sentences = [
    'query: 1452634 santool jawa 300 cl',
    'document: 1452634 santool съемник для сальников jawa 300 cl',
    'document: 1453934 santool съемник для сальников jawa 300 cl',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.1443, 0.1452],
#         [0.1443, 1.0000, 0.7490],
#         [0.1452, 0.7490, 1.0000]])
