What did I do :

• Today I watch youtube regarding the topic of the class, which is the neural network.
• Second, we discussed entropy, which is the uncertainty or randomness with a particular variable.
• Third, we discussed information gain, decision trees and so on, then do the exercise of one sample table.

Obstacles/Difficulties :

The difficulties of today to find out the entropy and information gain of one’s graph, there were many scattered data, and I was still confused about the meaning of the formula of calculation entropy amount.

What did I learn:
Today I learn about more about supervised learning, consists of neural network, entropy, information gain and decision tree construction.
