The Decision Trees algorithm is popular because it handles categorical data and works out of the box with multiclass classification tasks. You can extract the number of nodes in the decision tree as well as the tree depth of the model. Evaluate the Decision Tree model with BinaryClassification...

Logistic regression is an algorithm for binary classification.So let's start by setting up the problem. Here's an example of a binary classification problem. You might have an input of an image, like that,and want to output a label to recognize this image as being either a cat,in which...
