Nonparametric Instrumental Variable Regression through Stochastic Approximate Gradients

no code implementations8 Feb 2024 Caio Peixoto, Yuri Saporito, Yuri Fonseca

This paper proposes SAGD-IV, a novel framework for conducting nonparametric instrumental variable (NPIV) regression by employing stochastic approximate gradients to minimize the projected populational risk.

Contextual Inverse Optimization: Offline and Online Learning

no code implementations26 Jun 2021 Omar Besbes, Yuri Fonseca, Ilan Lobel

In the online setting, we leverage this geometric characterization to optimize the cumulative regret.

BooST: Boosting Smooth Trees for Partial Effect Estimation in Nonlinear Regressions

no code implementations10 Aug 2018 Yuri Fonseca, Marcelo Medeiros, Gabriel Vasconcelos, Alvaro Veiga

In this paper, we introduce a new machine learning (ML) model for nonlinear regression called the Boosted Smooth Transition Regression Trees (BooST), which is a combination of boosting algorithms with smooth transition regression trees.
