Lockout: Sparse Regularization of Neural Networks

no code implementations15 Jul 2021 Gilmer Valdes, Wilmer Arbelo, Yannet Interian, Jerome H. Friedman

Many regression and classification procedures fit a parameterized function $f(x;w)$ of predictor variables $x$ to data $\{x_{i}, y_{i}\}_1^N$ based on some loss criterion $L(y, f)$.

Conditional Super Learner

no code implementations13 Dec 2019 Gilmer Valdes, Yannet Interian, Efstathios D. Gennatas Mark J. Van der Laan

In this article we consider the Conditional Super Learner (CSL), an algorithm which selects the best model candidate from a library conditional on the covariates.

Tree-Structured Boosting: Connections Between Gradient Boosted Stumps and Full Decision Trees

no code implementations18 Nov 2017 José Marcio Luna, Eric Eaton, Lyle H. Ungar, Eric Diffenderfer, Shane T. Jensen, Efstathios D. Gennatas, Mateo Wirth, Charles B. Simone II, Timothy D. Solberg, Gilmer Valdes

Additive models, such as produced by gradient boosting, and full interaction models, such as classification and regression trees (CART), are widely used algorithms that have been investigated largely in isolation.
