Non-Commutative State Tracking with Input-Dependent Low-Rank Updates in Mamba-3
Hiroki Fujii, Masaki Yamakita
State tracking from sequential observations can require both retaining information and updating it by composing observed operations. We extend Mamba-3's diagonal transition with an…

Bilinear Input Modulation for Mamba: Koopman Bilinear Forms for Memory Retention and Multiplicative Computation
Hiroki Fujii, Masaki Yamakita
Selective State Space Models (SSMs), notably Mamba, employ diagonal state transitions that limit both memory retention and bilinear computational capacity. We propose a factorized…
