Pruning

The video tutorial explains the concept of pruning in both gardening and decision trees. It highlights how decision trees can grow large with unnecessary branches, affecting performance. Pruning, by removing low-value branches, can improve accuracy and efficiency. The tutorial covers two types of pruning: pre-pruning, which stops unnecessary branching early, and post-pruning, which removes branches after the tree is complete.
