Nonstochastic Bandits with Infinitely Many Experts

X. Flora Meng, Tuhin Sarkar, Munther A. Dahleh

We study the problem of nonstochastic bandits with expert advice, extending the setting from finitely many experts to any countably infinite set: A learner aims to maximize the tot…

Data Driven Estimation of Stochastic Switched Linear Systems of Unknown Order

Tuhin Sarkar, Alexander Rakhlin, Munther A. Dahleh

We address the problem of learning the parameters of a mean square stable switched linear systems (SLS) with unknown latent space dimension, or \textit{order}, from its noisy input…

Nonparametric Finite Time LTI System Identification

Tuhin Sarkar, Alexander Rakhlin, Munther A. Dahleh

We address the problem of learning the parameters of a stable linear time invariant (LTI) system or linear dynamical system (LDS) with unknown latent space dimension, or order, fro…

Near optimal finite time identification of arbitrary linear dynamical systems

Tuhin Sarkar, Alexander Rakhlin

We derive finite time error bounds for estimating general linear time-invariant (LTI) systems from a single observed trajectory using the method of least squares. We provide the fi…

Minimal Realization Problems for Jump Linear Systems

Tuhin Sarkar, Mardavij Roozbehani, Munther A. Dahleh

This paper addresses two fundamental problems in the context of jump linear systems (JLS). The first problem is concerned with characterizing the minimal state space dimension sole…

A Marketplace for Data: An Algorithmic Solution

Anish Agarwal, Munther Dahleh, Tuhin Sarkar

In this work, we aim to design a data marketplace; a robust real-time matching mechanism to efficiently buy and sell training data for Machine Learning tasks. While the monetizatio…

Robustness in Consensus Networks

Tuhin Sarkar, Mardavij Roozbehani, Munther A. Dahleh

We consider the problem of robustness in large consensus networks that occur in many areas such as distributed optimization. Robustness, in this context, is the scaling of performa…

Asymptotic Network Robustness

Tuhin Sarkar, Mardavij Roozbehani, Munther A. Dahleh

This paper examines the dependence of network performance measures on network size and considers scaling results for large networks. We connect two performance measures that are we…

Lossy Compression via Sparse Linear Regression: Computationally Efficient Encoding and Decoding

Ramji Venkataramanan, Tuhin Sarkar, Sekhar Tatikonda

We propose computationally efficient encoders and decoders for lossy compression using a Sparse Regression Code. The codebook is defined by a design matrix and codewords are struct…
