CoCondenser trained on MS MARCO

This is a SPLADE Sparse Encoder model finetuned from Luyu/co-condenser-marco on the msmarco dataset using the sentence-transformers library. It maps sentences & paragraphs to a 30522-dimensional sparse vector space and can be used for semantic search and sparse 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.

python

from sentence_transformers import SparseEncoder

# Download from the 🤗 Hub
model = SparseEncoder("tomaarsen/splade-cocondenser-msmarco-margin-mse-minilm-small")
# Run inference

    'Plus, the CBO said the Dreamers would bring an additional 80,000 immigrants to the U.S., adding to the liability. In total, the immigrants and their families would cost taxpayers $26.8 billion, but only pay back $.9 billion in taxes, the CBO said. The analysis found that roughly 3.25 million undocumented immigrants are eligible for Dreamer status, while only 2 million would apply and only 1.6 million would be accepted over the next decade.',

    'Sustain is defined as to support something or to endure a trial or hardship. 1  An example of sustain is for a foundation to support the house. 2  An example of sustain is to survive days without food or water.',

query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 30522] [3, 30522]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
