SPLADE v3 is an advanced sparse encoding model designed for semantic search and information retrieval. It converts sentences or paragraphs into high-dimensional sparse vectors (30,522 dimensions), enabling efficient indexing and search in large text corpora. Unlike dense approaches, it produces clear and interpretable representations, where each dimension corresponds to a term in the vocabulary, thereby enhancing the explainability of results. This model stands out for its optimized training, combining distillation techniques and margin learning to significantly improve its accuracy compared to previous versions. It is particularly well-suited for search systems requiring both performance and transparency, such as search engines or question-answering tools.
This checkpoint corresponds to a model that starts from SPLADE++SelfDistil (naver/splade-cocondenser-selfdistil), and is
trained with a mix of KL-Div and MarginMSE, with 8 negatives per query sampled from SPLADE++SelfDistil. We used the original MS MARCO
collection without the titles.

This is a SPLADE Sparse Encoder model. It maps sentences & paragraphs to a 30522-dimensional sparse vector space and can be used for semantic search and sparse retrieval.
SparseEncoder(
(0): MLMTransformer({'max_seq_length': 512, 'do_lower_case': False}) with MLMTransformer model: BertForMaskedLM
(1): SpladePooling({'pooling_strategy': 'max', 'activation_function': 'relu', 'word_embedding_dimension': 30522})
)
First install the Sentence Transformers library:
pip install -U sentence-transformers
Then you can load this model and run inference.
from sentence_transformers import SparseEncoder
# Download from the 🤗 Hub
model = SparseEncoder("naver/splade-v3")
# Run inference

"Answers from Ronald Petersen, M.D. Yes, Alzheimer's disease usually worsens slowly. But its speed of progression varies, depending on a person's genetic makeup, environmental factors, age at diagnosis and other medical conditions. Still, anyone diagnosed with Alzheimer's whose symptoms seem to be progressing quickly â\x80\x94 or who experiences a sudden decline â\x80\x94 should see his or her doctor.",

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)
