Conditional Distribution Estimation for Functional Responses with Random Forests
Poorbita Kundu, Antonio R. Linero
Many functional data analyses reduce random functions to scalar summaries or conditional mean curves. This is limiting when we wish to understand how covariates affect the distribu…
Active Subspaces in Infinite Dimension
Poorbita Kundu, Nathan Wycoff
Active subspace analysis uses the leading eigenspace of the gradient's second moment to conduct supervised dimension reduction. In this article, we extend this methodology to real-…
Decision Theoretic Subgroup Detection With Bayesian Machine Learning
Entejar Alam, Poorbita Kundu, Antonio R. Linero
We consider the problem of identifying promising subpopulations in terms of treatment effectiveness or treatment effect heterogeneity, from a Bayesian decision theoretic perspectiv…
Exceedance and force of centrality for functional data
Poorbita Kundu, Hang Zhou, Hans-Georg Müller
Exceedance refers to instances where a dynamic process surpasses given thresholds, e.g., the occurrence of a heat wave. We propose a novel exceedance framework for functional data,…
