Essays on Algorithmic Learning and Uncertainty Quantification
… three essays. The first, titled “Localization, Convexity, and Star Aggregation,” develops new analytical tools based upon the offset Rademacher complexity for studying stochastic optimization in non-convex domains, including statistical prediction and model aggregation problems. Using these …

Fast and Scalable Power System Learning, Analysis, and Planning
… of a group of devices with uncertainties and non-convex models can be captured with a quadratic classifier and using that classifier we can design a virtual battery model that best describes the aggregate flexibility. For power system analysis and planning, we have addressed fast probabilistic …

The construction of optimal socially responsible investment portfolios in South Africa using traditional and artificial intelligence techniques
… face challenges with complex non-linear and non-convex models. Recently, meta-heuristic artificial intelligence (AI) algorithms have enhanced portfolio construction by addressing such constraints. Socially responsible investment (SRI) has gained popularity for its focus on sustainability, but …

A new scheme for the optimum design of stiffened composite panels with geometric imperfections
… methodology in which a manufacturing model and a convex model for uncertainties are used in conjunction with a nonlinear design tool in order to obtain a more realistic, better performing final design. First a finite element code for the nonlinear postbuckling analysis of stiffened panels is …

Optimization Algorithms for Structured Machine Learning and Image Processing Problems
… (ii) we further investigate sparse linear models with two commonly adopted general sparsity-inducing regularization terms, the overlapping Group Lasso penalty l1/l2-norm and the l1/l_infty-norm. We propose a unified framework based on the augmented Lagrangian method, under which problems …
