Limitations of a decision tree
NettetOverfitting: Decision trees tend to overfit, which makes them less robust as they are sensitive and prone to sampling errors. It can be reduced by hyperparameter tuning like by setting the max-depth, min samples split, min samples leaf, max-leaf nodes, min impurity split. We can tune it using GridSearchCV and cross-validation and by evaluating ... NettetA decision tree is a non-parametric supervised learning algorithm, which is utilized for both classification and regression tasks. It has a hierarchical, tree structure, which …

NettetDraw the tree from left to right. A square represents a Decision. A circle represents an Outcome. At a Decision Square - a branch from it represents a potential event - with a probability of it happening attached. Figure 1: There are two branches coming off the initial decision point - the top branch has a certain outcome. NettetA decision tree is undoubtedly very fast as compared to other techniques, the only thing that limits it is the condition of overfitting that arises when the trees grow and become complex or dense, in order to overcome the problem of overfitting, we should use the random forest, i.e nothing but the group of decision trees that performs decision …

The problem of learning an optimal decision tree is known to be NP-complete under several aspects of optimality and even for simple concepts. Consequently, practical decision-tree learning algorithms are based on heuristic algorithms such as the greedy algorithm where locally optimal decisions are made at each node. 1024×768
