Certainty Equivalent Quadratic Control for Markov Jump Systems
Zhe Du, Yahya Sattar, Davoud Ataee Tarzanagh +3
Real-world control applications often involve complex dynamics subject to abrupt changes or variations. Markov jump linear systems (MJS) provide a rich framework for modeling such…
Preference Modeling with Context-Dependent Salient Features
Amanda Bower, Laura Balzano
We consider the problem of estimating a ranking on a set of items from noisy pairwise comparisons given item features. We address the fact that pairwise comparison data often refle…
Online matrix factorization for Markovian data and applications to Network Dictionary Learning
Hanbaek Lyu, Deanna Needell, Laura Balzano
Online Matrix Factorization (OMF) is a fundamental tool for dictionary learning problems, giving an approximate representation of complex data sets in terms of a reduced number of…
Mode Clustering for Markov Jump Systems
Zhe Du, Necmiye Ozay, Laura Balzano
In this work, we consider the problem of mode clustering in Markov jump models. This model class consists of multiple dynamical modes with a switching sequence that determines how…
A Memory-efficient Algorithm for Large-scale Sparsity Regularized Image Reconstruction
Greg Ongie, Naveen Murthy, Laura Balzano +1
We derive a memory-efficient first-order variable splitting algorithm for convex image reconstruction problems with non-smooth regularization terms. The algorithm is based on a pri…
Streaming PCA and Subspace Tracking: The Missing Data Case
Laura Balzano, Yuejie Chi, Yue M. Lu
For many modern applications in science and engineering, data are collected in a streaming fashion carrying time-varying information, and practitioners need to process them with a…
