WebJul 30, 2024 · Random forests are a powerful method for non-parametric regression, but are limited in their ability to fit smooth signals, and can show poor predictive performance in the presence of strong, smooth effects. Taking the perspective of random forests as an adaptive kernel method, we pair the forest kernel with a local linear regression … WebThe minimum weighted fraction of the sum total of weights (of all the input samples) required to be at a leaf node.
