LAB: Entropy Calculation – Example
In previous section, we studied about How Decision tree Splits works?
- Calculate entropy at the root for the given population
- Calculate the entropy for the two distinct gender segments
Code- Entropy Calculation
- Entropy at root 100%
- Male Segment : (-48/60)log(48/60,2)-(12/60)log(12/60,2)
- 0.7219281
- FemaleSegment : (-2/40)log(2/40,2)-(38/40)log(38/40,2)
- 0.286397
The next post is about Information Gain in Decision tree Split.
