Transfer in Sequential Multi-armed Bandits via Reward Samples

no code implementations19 Mar 2024 Rahul N R, Vaibhav Katewa

We consider a sequential stochastic multi-armed bandit problem where the agent interacts with bandit over multiple episodes.

Approximate Stability Radius Analysis and Design in Linear Systems

no code implementations18 Mar 2024 Ananta Kant Rai, Vaibhav Katewa

The robustness of the stability properties of dynamical systems in the presence of unknown/adversarial perturbations to system parameters is a desirable property.

Minimum-norm Sparse Perturbations for Opacity in Linear Systems

1 code implementation30 Jun 2023 Varkey M John, Vaibhav Katewa

In this paper, we propose algorithms to compute the minimum sparse perturbation to be added to a system to make its initial states opaque.

On Connections between Opacity and Security in Linear Systems

no code implementations13 Jun 2022 Varkey M. John, Vaibhav Katewa

In this paper, we show that a fundamental trade-off exists between these properties for a linear dynamical system, in the sense that if an opaque system is subjected to attacks, all attacks cannot be detected.

Behavioral Feedback for Optimal LQG Control

no code implementations1 Apr 2022 Abed AlRahman Al Makdah, Vishaal Krishnan, Vaibhav Katewa, Fabio Pasqualetti

In this work, we revisit the Linear Quadratic Gaussian (LQG) optimal control problem from a behavioral perspective.

Robust Adversarial Classification via Abstaining

no code implementations6 Apr 2021 Abed AlRahman Al Makdah, Vaibhav Katewa, Fabio Pasqualetti

We propose metrics to quantify the nominal performance of a classifier with an abstain option and its robustness against adversarial perturbations.

On the Robustness of Data-Driven Controllers for Linear Systems

no code implementations L4DC 2020 Rajasekhar Anguluri, Abed AlRahman Al Makdah, Vaibhav Katewa, Fabio Pasqualetti

This paper proposes a new framework and several results to quantify the performance of data-driven state-feedback controllers for linear systems against targeted perturbations of the training data.

A Fundamental Performance Limitation for Adversarial Classification

no code implementations4 Mar 2019 Abed AlRahman Al Makdah, Vaibhav Katewa, Fabio Pasqualetti

Despite the widespread use of machine learning algorithms to solve problems of technological, economic, and social relevance, provable guarantees on the performance of these data-driven algorithms are critically lacking, especially when the data originates from unreliable sources and is transmitted over unprotected and easily accessible channels.
