New research probes multi-layer SSMs' expressive power and limitations

A new paper explores the expressive power and limitations of multi-layer state-space models (SSMs). Researchers analyzed how factors like depth, precision, state dimension, and chain-of-thought (CoT) reasoning impact these models. The study provides theoretical bounds for solving specific sequential information propagation problems and distinguishes between post-input and input-interleaved reasoning. AI

IMPACT Provides theoretical insights into the capabilities and constraints of state-space models, potentially influencing future architectural designs.

RANK_REASON The cluster contains a research paper detailing theoretical analysis of multi-layer state-space models. [lever_c_demoted from research: ic=1 ai=1.0]

    On the Expressive Power and Limitations of Multi-Layer SSMs

    arXiv:2604.14501v2 Announce Type: replace-cross Abstract: We study how depth, finite precision, state dimension, and chain-of-thought (CoT) affect the expressive power of multi-layer state-space models (SSMs). For the explicit-table $K$-function-composition problem, a canonical b…
