Constrained optimization as ecological dynamics with applications to random quadratic programming in high dimensions
Pankaj Mehta, Wenping Cui, Ching-Hao Wang +1
Quadratic programming (QP) is a common and important constrained optimization problem. Here, we derive a surprising duality between constrained optimization with inequality constra…
Bayesian feature selection with strongly-regularizing priors maps to the Ising Model
Charles K. Fisher, Pankaj Mehta
Identifying small subsets of features that are relevant for prediction and/or classification tasks is a central problem in machine learning and statistics. The feature selection ta…
Statistical mechanics of transcription-factor binding site discovery using Hidden Markov Models
Pankaj Mehta, David Schwab, Anirvan M. Sengupta
Hidden Markov Models (HMMs) are a commonly used tool for inference of transcription factor (TF) binding sites from DNA sequence data. We exploit the mathematical equivalence betwee…
