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…

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…

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…

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^{…
