Kronecker Product Attention: Memory-Efficient KV Compression via Structured Factorization

View original on arxiv.org

Overview

arXiv:2610.12657v1 Announce Type: new Abstract: Efficient autoregressive generation is increasingly limited by the memory footprint of the key-value (KV) cache, which grows linearly with sequence length, batch size, and model depth. Existing approaches such as Multi-Query Attention (MQA), Grouped-Query Attention (GQA), Multi-Head Latent Attention (MLA), and Tensor Product Attention (TPA) reduce this cost through different trade-offs, but often sacrifice expressivity, require additional positiona
