ML-#03 - Decision Tree.

Basically the idea is pokenmon or whatsapp you decide which field is important and keep cutting the line based on that and keep repeating it.

Entropy is basically chances to fail use the basic probability and then multipl to get them result but log to get the reverse which is entropy.

Basically you take the data set and devide by entropy of different keys and then keep recording information gain and keep repeating the same.

Based on the probability calculate entropy and then information gain. and create the tree.
