A Look at the UniformRobust Method for Histogram Type
by Hannah Tillman, Megan Kurka | July 25, 2023 GBM , H2O-3

Tree-based algorithms, especially Gradient Boosting Machines (GBM’s), are one of the most popular algorithms used. They often out-perform linear models and neural networks for tabular data since they used a boosted approach where each tree built works to fix the error of the previous tree. As the model trains, it is continuously self-corr...
