A family of learned sparse neural retrieval models that produce sparse vocabulary-space representations for queries and documents.

Also called

Sparse Lexical and Expansion Model

Scope

SPLADE learns sparse expansion-like activations and is commonly used for first-stage retrieval or ranking. It is an implementation/model family within learned sparse retrieval, not a synonym for either learned sparse retrieval generally or query expansion.
