Machine Learning: Random Forest with Python from Scratch - Information Gain

The video tutorial explains the concept of information gain and its importance in constructing decision trees. It discusses how information gain helps in deciding which questions to ask at each node by calculating the impurity and partitioning the dataset. The tutorial also covers the implementation of information gain using Python, detailing the steps involved in calculating it for different nodes. The session concludes with a brief overview of the next lecture, which will focus on finding the best split using the methods discussed.
