Sara Shashaani Department of Industrial and Systems Engineering North Carolina State University Title: Adaptive Sampling with Trust-region Optimization for Nonconvex Stochastic Functions. Abstract: Simulation Optimization problems are often non-convex, derivative-free, and with stochastic noise that may be notably heteroskedastic. There is … Read more

Generative modeling with trees and recursive partitions Trees and recursive partitions are most well-known in supervised learning for predictive tasks, such as regression and classification. Famous examples include CART and its various forms of ensembles—e.g., random forest and boosting. A … Read more

Unbiased Estimators from Biased Algorithms In many Monte Carlo settings, one wishes to compute the expectation of a stochastic object that can only be approximated. In such settings, the natural Monte Carlo estimator will be biased. In work of McLeish … Read more
SAIL Speaker Series presents: Women in Sports Analytics A conversation in sports analytics from the perspectives of four women from different backgrounds with unique contributions to the field. Students will … Read more
Statistical Inference for Markov Chains with Known Structure In this talk, we will discuss nonparametric estimation for Markov chains that satisfy stochastic recursions of a known form, but in which the driving noise has an unknown distribution. We assume that … Read more
