FastBDT: A speed-optimized and cache-friendly implementation of stochastic gradient-boosted decision trees for multivariate classification Stochastic gradient-boosted decision trees are widely employed for multivariate classification and regression tasks. This paper presents a speed-optimized and cache-friendly...
ggBRT contains a set of R functions that use ggplot2 (Wickham 2016) to explore and visualize the results of boosted regression trees fitted with the gbm.step routine (Elith et al 2008) in the dismo package (Hijmans et al. 2017). The package is designed to facilitate the exploration and ...
This is the first study to assess the risk of co-endemicandtransmission in the Peruvian Amazon using boosted regression tree (BRT) models based on social and environmental predictors derived from satellite imagery and data. Yearly cross-validated BRT models were created to discriminate high-risk (...
The final BRT model can be understood as an additive regression model in which individual terms are simple trees, fitted in a forward, stagewise fashion. Boosted regression trees incorporate important advantages of tree-based methods, handling different types of predictor variables and accommodating ...

Compared with the existing conditional preference model, boosted regression trees can process large amounts of data in recommendation systems due to the reasonable storage space and low learning complexity. We integrate boosted regression trees into the framework of matrix factorization, and propose an ...
