The feature with the optimal split i.e., the highest value of information gain at a node of a decision tree is used as the feature for splitting the node. The concept of information gain function falls under the C4.5 algorithm for generating the decision trees and selecting the optimal split for a decision tree node. [1] Some of its advantages ...
In decision tree learning, information gain ratio is a ratio of information gain to the intrinsic information. It was proposed by Ross Quinlan , [ 1 ] to reduce a bias towards multi-valued attributes by taking the number and size of branches into account when choosing an attribute.
The leaves will represent the final classification decision the model has produced based on the mutations a sample either has or does not have. The left tree is the decision tree we obtain from using information gain to split the nodes and the right tree is what we obtain from using the phi function to split the nodes.
C4.5 is an algorithm used to generate a decision tree developed by Ross Quinlan. [1] C4.5 is an extension of Quinlan's earlier ID3 algorithm.The decision trees generated by C4.5 can be used for classification, and for this reason, C4.5 is often referred to as a statistical classifier.

Can you lose weight with volume eating? Yes, you can lose weight with volume eating. “It can be a really useful approach for weight management,” Cording says.
Weight loss is a personal for everyone, so it’s hard to say that you’ll drop pounds just by having more protein and fiber in your diet. However, eating both may help you feel fuller for longer.
