@rajistics: Entropy can be a useful measure in machine learning. Entropy and information gain is used in building decision trees. I have also seen entropy used in feature engineering. Here is a short conceptual understanding for entropy. This video is based on the excellent blog post on entropy (that also provides the math) #datascience #machinelearning #featureengineering #informationgain #entropy #decisiontrees Background Photo: Hans-Peter Gauster https://unsplash.com/photos/3y1zF4hIPCg Entropy: How Decision Trees Make Decisions by Sam T: https://towardsdatascience.com/entropy-how-decision-trees-make-decisions-2946b9c18c8
