Web3 jul. 2024 · Information gain helps to determine the order of attributes in the nodes of a decision tree. The main node is referred to as the parent node, whereas sub-nodes are … WebIn decision tree learning, Information gain ratio is a ratio of information gain to the intrinsic information. It was proposed by Ross Quinlan, to reduce a bias towards multi-valued attributes by taking the number and size of branches into account when choosing an attribute.. Information Gain is also known as Mutual Information.
Web11 jan. 2024 · We simply subtract the entropy of Y given X from the entropy of just Y to calculate the reduction of uncertainty about Y given an additional piece of information X about Y. This is called Information Gain. The greater the reduction in this uncertainty, the more information is gained about Y from X.
