When features are on the various scales, it is also fine. Roughly speaking, with Random Forest you can use data as they are. SVM maximizes the "margin" and thus relies on the concept of "distance" between different points. It is up to you to decide if "distance" is ... choking eyesWebClassification and Regression Trees (CART) are a relatively old technique (1984) that is the basis for more sophisticated techniques.Benefits of decision trees include that they can be used for both regression and classification, they don’t require feature scaling, and they are relatively easy to interpret as you can visualize decision trees. choking fact sheetWebFeb 16, 2024 · One main difference of classification trees and logistic regression is that the former outputs classes (-1,1) while the logistic regression outputs probs. One idea is to choose the best feature X from a set of features and pick up a threshold (0.5?) to convert the probs to classes and then use a weighted logistic regression to find the next feature etc. gray short wigs for older womenWebJun 3, 2016 · GBT is a good method especially if you have mixed feature types like categorical, numerical and such.
