Sparse Transformer

Neural Networks· Advanced

Definition

A transformer variant that computes attention over a sparse subset of token pairs rather than all pairs, reducing attention complexity from O(n²) to O(n√n) or similar. Enables processing of much longer sequences than standard transformers at comparable computational cost.

Enterprise Context

Relevant for enterprise document processing applications — extremely long documents (full contracts, research reports) benefit from sparse attention architectures.
