Suppose you are building random forest model, which split a node on the attribute, that has highest information gain. In the below image, select the attribute which has the highest information gain? A) Outlook B) Humidity C) Windy D) Temperature. The Solution mentions "Solution: A. Information gain increases with the average purity of subsets.


The random forest has a solution to this- that is, for each split, it selects a random set of subset predictors so each split will be different. So more strong predictors cannot overshadow other fields and hence we get more diverse forests.

Random Forest Classifier — Pyspark Implementation. Now, we will train a Random Forest Classifier in Pyspark. Note that we will use the same Iris dataset as before and the same training/testing data to compare the accuracies of both algorithms. Random forest is one of the most widely used machine learning algorithms in real production settings. 1. Introduction to random forest regression. Random forest is one of the most popular algorithms for regression problems (i.e.

However, it might 'arguably' fasten the convergence as hinted in other answers 2019-03-29 · When training a decision tree, the best split is chosen by maximizing the Gini Gain, which is calculated by subtracting the weighted impurities of the branches from the original impurity. Want to learn more? Check out my explanation of Information Gain, a similar metric to Gini Gain, or my guide Random Forests for Complete Beginners.

Random forests are also good at handling large datasets with high dimensionality and heterogeneous feature types (for example, if one column is categorical and another is numerical). Random forest is an ensemble classifier based on bootstrap followed by aggregation (jointly referred as bagging).
