Overfitting
Remove the tree top or stop it from growing. Overfitting is the situation when the model gets trained from the random chatter of the training data instead of its trends. Combining is cutting off an unneeded stream of information that is of no importance to the tree.
- Example: In a marketing campaign, a decision tree model may overfit if it captures noise in the data as significant patterns, leading to targeting the wrong audience segment.
- Prevention: Use techniques like pruning or limiting the tree depth to prevent overfitting and focus on capturing meaningful patterns.
