What is a GBM ensemble?

ChatGPT:

“GBM” refers to Gradient Boosting Machine (GBM), which is a type of machine learning algorithm used for regression and classification problems.

GBM works by building a set of weak prediction models, usually shallow decision trees, sequentially. At each stage, a new decision tree is fit to the residuals (errors) of the previous model. Then, the result of all the trees is combined to obtain a final prediction.

This approach of sequentially building weak models and correcting the errors of the previous model allows GBM to create a robust and accurate predictive model. It is known for its ability to handle high-dimensional data, manage nonlinear relationships, and handle different types of data (categorical and numerical).

GBM is an ensemble technique because it combines multiple simpler models to form a stronger and more accurate model. Additionally, it can deliver excellent results across a wide range of machine learning problems.

In summary, a GBM ensemble is a machine learning model that uses the Gradient Boosting Machine algorithm to create a predictive model from a collection of weak models.
