WitrynaIt is based on Decision Trees using the decision histogram, which provides the possibility to follow the path of the expected least loss in time [38,39]. In comparison to XGBoost, LGBM has vertical growth (leaf-wise) that results in more loss reduction, and it tends to a higher accuracy, while XGBoost has horizontal growth (level-wise). WitrynaSome advantages of decision trees are: Simple to understand and to interpret. Trees can be visualized. Requires little data preparation. Other techniques often require data normalization, dummy variables need to be created and blank values to be removed. Note however that this module does not support missing values.
