GBM and Random Forest are both ensemble learning techniques used in machine learning, but they have some key differences.
GBM (Gradient Boosting Machine) builds trees sequentially, each tree correcting errors of the previous one, while Random Forest builds trees independently.
GBM is more prone to overfitting compared to Random Forest, as it continues to minimize errors in subsequent trees.
Random Forest is generally fast...
Test data is used to evaluate the performance of a model during training, while out-of-time (OOT) data is used to evaluate the model's performance on unseen data.
Test data is typically a subset of the original dataset used to train the model.
OOT data is data that was not available at the time of model training and is used to simulate real-world scenarios.
Test data helps assess how well the model generalizes to new, uns...
