Question 4

When selecting an appropriate ML approach, which of the following guidelines does NOT apply?

Options :

A : Reinforcement learning is better suited to contexts in which there is interaction with the environment.

B : For unsupervised learning, it is necessary to have properly labeled data.

C :

There should be sufficient training and test data available for the selected ML approach.

D : If the problem involves the notion of multiple states, and involves decisions at each state, then reinforcement learning may be applicable.

Answer: B
