Machine Learning Random Forest with Python from Scratch - Best Slip

The video tutorial explains how to find the best split in decision trees by implementing a function in Python. It covers the calculation of Gini impurity, iterating over features and values, and partitioning data to calculate information gain. The goal is to identify the best question to ask at each node to minimize impurity and maximize information gain, ultimately leading to a decision node or leaf node. The tutorial concludes with a review of the function and a preview of the next lesson on creating decision and leaf nodes.

Explain the role of unique values in determining the best split.

What happens if the length of true rows or false rows is zero?

What criteria are used to determine the best question to ask at a node?

Discuss the importance of reaching a leaf node in decision trees.
