Prediction performance of linear models and gradient boosting machine on complex phenotypes in outbred mice

open access: yesG3: Genes, Genomes, Genetics, 2022
We compared the performance of linear (GBLUP, BayesB, and elastic net) methods to a nonparametric tree-based ensemble (gradient boosting machine) method for genomic prediction of complex traits in mice. The dataset used contained genotypes for 50,112 SNP

Using machine learning to improve risk prediction in durable left ventricular assist devices.

open access: yesPLoS ONE, 2021
Risk models have historically displayed only moderate predictive performance in estimating mortality risk in left ventricular assist device therapy. This study evaluated whether machine learning can improve risk prediction for left ventricular assist ...

Federated Functional Gradient Boosting

open access: yesCoRR, 2021
In this paper, we initiate a study of functional minimization in Federated Learning. First, in the semi-heterogeneous setting, when the marginal distributions of the feature vectors on client machines are identical, we develop the federated functional gradient boosting (FFGB) method that provably converges to the global minimum. Subsequently, we extend

Individually Fair Gradient Boosting

open access: yesCoRR, 2021
We consider the task of enforcing individual fairness in gradient boosting. Gradient boosting is a popular method for machine learning from tabular data, which arise often in applications where algorithmic fairness is a concern. At a high level, our approach is a functional gradient descent on a (distributionally) robust loss function that encodes our ...

Boost-R: Gradient boosted trees for recurrence data [PDF]

open access: yesJournal of Quality Technology, 2021
Recurrence data arise from multi-disciplinary domains spanning reliability, cyber security, healthcare, online retailing, etc. This paper investigates an additive-tree-based approach, known as Boost-R (Boosting for Recurrence Data), for recurrent event data with both static and dynamic features.
