Max Bin
Parameter controlling the maximum number of bins in the histogram algorithm, balancing training speed and model accuracy.
terms
Leaf-wise vs Level-wise
Comparison of growth strategies: leaf-wise optimizes local loss reduction while level-wise uniformly develops all nodes at a level.
terms
Missing Value Handling
LightGBM's built-in capability to automatically handle missing values by assigning them to the optimal direction during each split.
terms
Regularization Lambda
Lambda_l1 and lambda_l2 parameters applying L1 (Lasso) and L2 (Ridge) regularization respectively to control model complexity.
terms
Histogram Pooling
LightGBM's memory optimization technique reusing histograms between iterations to reduce dynamic memory allocation.
