Learning summary

Bootstrap samplingEach tree receives a different resampled training set. Duplicate and out-of-bag records create useful variation.
Random feature subsetsEach split considers only some features. This reduces tree correlation and prevents one feature dominating every tree.
Voting and averagingClassification uses combined votes. Regression averages tree predictions, reducing unstable errors from individual trees.
