Maximizing and Satisficing in Multi-armed Bandits with Graph Information

Autor: Thaker, Parth K., Malu, Mohit, Rao, Nikhil, Dasarathy, Gautam

Pure exploration in multi-armed bandits has emerged as an important framework for modeling decision-making and search under uncertainty. In modern applications, however, one is often faced with a tremendously large number of options. Even obtaining o

Differentiable Programming for Hyperspectral Unmixing using a Physics-based Dispersion Model

Autor: Janiczek, John, Thaker, Parth, Dasarathy, Gautam, Edwards, Christopher S., Christensen, Philip, Jayasuriya, Suren

Hyperspectral unmixing is an important remote sensing task with applications including material identification and analysis. Characteristic spectral features make many pure materials identifiable from their visible-to-infrared spectra, but quantifyin

On the Sample Complexity and Optimization Landscape for Quadratic Feasibility Problems

Autor: Thaker, Parth, Dasarathy, Gautam, Nedić, Angelia

We consider the problem of recovering a complex vector $\mathbf{x}\in \mathbb{C}^n$ from $m$ quadratic measurements $\{\langle A_i\mathbf{x}, \mathbf{x}\rangle\}_{i=1}^m$. This problem, known as quadratic feasibility, encompasses the well known phase
