Feature Selection for Personalized Policy Analysis

no code implementations31 Dec 2022 Maria Nareklishvili, Nicholas Polson, Vadim Sokolov

In particular, our method is able to capture policy effect heterogeneity both within and across subgroups of the population defined by observable characteristics.

Gambits: Theory and Evidence

no code implementations5 Oct 2021 Shiva Maharaj, Nicholas Polson, Christian Turk

This allows us to calculate the $Q$-values of a Gambit where material (usually a pawn) is sacrificed for dynamic play.

Bayesian Inference for Gamma Models

no code implementations3 Jun 2021 Jingyu He, Nicholas Polson, Jianeng Xu

We use the theory of normal variance-mean mixtures to derive a data augmentation scheme for models that include gamma functions.

Deep Learning: Computational Aspects

no code implementations26 Aug 2018 Nicholas Polson, Vadim Sokolov

In this article we review computational aspects of Deep Learning (DL).

Posterior Concentration for Sparse Deep Learning

no code implementations NeurIPS 2018 Nicholas Polson, Veronika Rockova

As an aside, we show that SS-DL does not overfit in the sense that the posterior concentrates on smaller networks with fewer (up to the optimal number of) nodes and links.

Sparse Regularization in Marketing and Economics

no code implementations1 Sep 2017 Guanhao Feng, Nicholas Polson, Yuexi Wang, Jianeng Xu

Alpha-norm, in contrast to lasso and ridge regularization, jumps to a sparse solution.
