GPBoost is a software library for combining tree-boosting with Gaussian process and grouped random effects models (aka mixed effects models or latent Gaussian models). It also allows for independently applying tree-boosting as well as Gaussian process and (generalized) linear mixed effects models (LMMs and GLMMs). clutter house floor plan

"WebAug 24, 2024 · The above Boosted Model is a Gradient Boosted Model which generates 10000 trees and the shrinkage parameter lambda = 0.01 l a m b d a = 0.01 which is also a sort of learning rate. Next parameter is the interaction depth d d which is the total splits we want to do.So here each tree is a small tree with only 4 splits. " - Boost r tree
