Online Ranking with Constraints: A Primal-Dual Algorithm and Applications to Web Traffic-Shaping
Parikshit Shah, Akshay Soni, Troy Chevalier
We study the online constrained ranking problem motivated by an application to web-traffic shaping: an online stream of sessions arrive in which, within each session, we are asked…
Relative Entropy Relaxations for Signomial Optimization
Venkat Chandrasekaran, Parikshit Shah
Signomial programs (SPs) are optimization problems specified in terms of signomials, which are weighted sums of exponentials composed with linear functionals of a decision variable…
Conic Geometric Programming
Venkat Chandrasekaran, Parikshit Shah
We introduce and study conic geometric programs (CGPs), which are convex optimization problems that unify geometric programs (GPs) and conic optimization problems such as semidefin…
Linear System Identification via Atomic Norm Regularization
Parikshit Shah, Badri Narayan Bhaskar, Gongguo Tang +1
This paper proposes a new algorithm for linear system identification from noisy measurements. The proposed algorithm balances a data fidelity term with a norm induced by the set of…
An Optimal Controller Architecture for Poset-Causal Systems
Parikshit Shah, Pablo Parrilo
We propose a novel and natural architecture for decentralized control that is applicable whenever the underlying system has the structure of a partially ordered set (poset). This c…
H_2-Optimal Decentralized Control over Posets: A State-Space Solution for State-Feedback
Parikshit Shah, Pablo A. Parrilo
We develop a complete state-space solution to H_2-optimal decentralized control of poset-causal systems with state-feedback. Our solution is based on the exploitation of a key sepa…
