A Deep State-Space Model Compression Method using Upper Bound on Output Error

Hiroki Sakamoto, Kazuhiro Sato

We study deep state-space models (Deep SSMs) that contain linear quadratic-output (LQO) systems as internal blocks and present a compression method with a provable output error gua…

Data-Driven Regularized Time-Limited h2 Model Reduction from Noisy Impulse Responses

Hiroki Sakamoto, Kazuhiro Sato

This paper develops a data-driven time-limited h2 model reduction method for discrete-time linear time-invariant systems. Specifically, we formulate and solve a regularized time-li…

Data-driven h2 model reduction for linear discrete-time systems

Hiroki Sakamoto, Kazuhiro Sato

We present a data-driven framework for h2-optimal model reduction for linear discrete-time systems. Our main contribution is to create optimal reduced-order models in the $h^{…

Compression Method for Deep Diagonal State Space Model Based on H2 Optimal Reduction

Hiroki Sakamoto, Kazuhiro Sato

Deep learning models incorporating linear SSMs have gained attention for capturing long-range dependencies in sequential data. However, their large parameter sizes pose challenges…
