WebThe decision trees have a unidirectional tree structure i.e. at every node the algorithm makes a decision to split into child nodes based on certain stopping criteria. Most commonly DTs use entropy, information gain, Gini index, etc. There are a few known algorithms in DTs such as ID3, C4.5, CART, C5.0, CHAID, QUEST, CRUISE. 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 …
