One hit encoding Decision Tree Data Preprocessing data

[Aman6]

I did not understand how we use features that were one hot encoded in decision tree. How to do they split at each node with calculating information gain.

Hi @Aman6
Original Dataset:

Numeric	Category
5	Red
8	Blue
3	Green
6	Yellow
After One-Hot Encoding and Removing the “Category” Column:

Numeric	Red	Blue	Green	Yellow
5	1	0	0	0
8	0	1	0	0
3	0	0	1	0
6	0	0	0	1

after we convet the data we deal with it like any another dataset
