Question 55

+2 marksOne or more correct options

Consider the following code snippet that trains a Decision Tree classifier using scikit-learn:

A node in the trained decision tree is split only if both of the following conditions are satisfied: • The node contains at least min_samples_split samples. • Each child node created after the split contains at least min_samples_leaf samples. Assume node (N) is a non-leaf node being considered for splitting. In which of the following cases will the split at node (N) be allowed?

Consider the following code snippet that trains a Decision Tree classifier using scikit-learn:

Select all that apply.

  1. A

    Node (N) contains 15 samples. After splitting, the left child has 9 samples and the right child has 6 samples.

  2. B

    Node (N) contains 6 samples. After splitting, the left child has 4 samples and the right child has 2 samples.

  3. C

    Node (N) contains 12 samples. After splitting, the left child has 3 samples and the right child has 9 samples.

  4. D

    Node (N) contains 8 samples. After splitting, the left child has 4 samples and the right child has 4 samples.
