WebbEvaluating the prediction of an ensemble typically requires more computation than evaluating the prediction of a single model. In one sense, ensemble learning may be thought of as a way to compensate for poor learning algorithms by performing a lot of extra computation. On the other hand, the alternative is to do a lot more learning on one … WebbLearning tree structure is much harder than traditional optimization problem where you can simply take the gradient. It is intractable to learn all the trees at once. Instead, we use an …

WebbIn decision tree learning, there are numerous methods for preventing overfitting. These may be divided into two categories: Techniques that stop growing the tree before it reaches the point where it properly classifies the training data. Then post-prune the tree, and ways that allow the tree to overfit the data and then post-prune the tree.
