Learning and enforcing diversity with Determinantal Point Processes
… we approach this problem using Determinantal Point Processes (DPPs), probabilistic models that provide an intuitive and powerful way of balancing quality and diversity in sets of items. We introduce a novel, fixed-point algorithm for estimating the maximum likelihood parameters of a DPP, …

Implicit Fixed-point Proximity Framework for Optimization Problems and Its Applications
… challenging and numerically difficult. The fixed-point proximity framework that we will systematically study in this dissertation provides a direct and unified methodology for finding solutions to those optimization problems. The framework approaches the models arising from applications …

Dynamic Discrete Choice Estimation using Reinforcement Learning with Applications in Online Food Markets
… parallels with DDC methods including Nested Fixed-Point Algorithm (NFXP), Conditional Choice Simulation (CCS), and Nested Pseudo-Likelihood (NPL). The chapter discusses how incorporating both tabular RL methods and those using function or policy approximation into the DDC estimation process …

Secure Gaussian sampling for lattice-based signatures: new directions for reaching high standard deviation
… work in this thesis aims to explore candidate algorithms for the secure sampling of Gaussian distributions with high standard deviation.<br/><br/>The sampling methods chosen for this research are all well-suited to producing wide distributions, in that their complexities do not grow with the …
