On Sample Complexity Bounds for Frequency-Domain System Identification
Arya Honarpisheh, Mario Sznaier
We study the sample complexity of frequency-domain system identification with bounded measurement noise. We focus on interpolatory identification algorithms, which return models co…
TrajEdit: Real-Time Flow-Matching Trajectory Adaptation via FlowEdit and CBF Safety Filter
Wondmgezahu Teshome, Arya Honarpisheh, Octavia Camps +1
Safe, real-time motion planning is especially difficult when a dynamic obstacle actively pursues the ego agent, requiring rapid adaptation as the environment changes. We present Tr…
Frequency Response Identification of Low-Order Systems: Finite-Sample Analysis
Arya Honarpisheh, Mario Sznaier
This paper proposes a frequency-domain estimator for low-order systems from repeated noisy measurements. The estimator minimizes a quadratic data-fitting term regularized by the nu…
Safe Control for Pursuit-Evasion with Density Functions
Mustafa Bozdag, Arya Honarpisheh, Mario Sznaier
This letter presents a density function based safe control synthesis framework for the pursuit-evasion problem. We extend safety analysis to dynamic unsafe sets by formulating a re…
Challenges in Model Agnostic Controller Learning for Unstable Systems
Mario Sznaier, Mustafa Bozdag
Model agnostic controller learning, for instance by direct policy optimization, has been the object of renewed attention lately, since it avoids a computationally expensive system…
A Hybrid Framework for Efficient Koopman Operator Learning
Alexander Estornell, Leonard Jung, Alenna Spiro +2
Koopman analysis of a general dynamics system provides a linear Koopman operator and an embedded eigenfunction space, enabling the application of standard techniques from linear an…
Generalization Error Analysis for Selective State-Space Models Through the Lens of Attention
Arya Honarpisheh, Mustafa Bozdag, Octavia Camps +1
State-space models (SSMs) have recently emerged as a compelling alternative to Transformers for sequence modeling tasks. This paper presents a theoretical generalization analysis o…
