Decision tree search algorithm
WebMay 1, 2024 · $\begingroup$ Thank you. I think I haven't fully understood this whole topic of decision-trees and got things mixed up. I learned about it in sort of an informal way in the context of showing that every comparison-based algorithm has a lower bound of $ \Omega(n log n) $ in W.C. and couldn't establish a grip understanding of what a … WebIn a decision tree, for predicting the class of the given dataset, the algorithm starts from the root node of the tree.

WebJun 3, 2024 · The decision tree algorithm is a popular supervised machine learning algorithm for its simple approach to dealing with complex datasets. Decision trees get the name from their resemblance to a tree that includes roots, branches and leaves in the form of nodes and edges. WebThe algorithm's optimality can be improved by using backtracking during the search for the optimal decision tree at the cost of possibly taking longer. ID3 can overfit the training data. To avoid overfitting, smaller decision trees should be preferred over larger ones.
