I have to decide for which value of "Klasse"
How do i do it?
I know that I have to decide on maximum information gain
So first off I've calculated the entropy of "Klasse"
That is E(Klasse)= -(3/11*log(3/11)+3/11*log(3/11)+5/11*log(5/11)) = 1.067
So how do I proceed from that?
I now need to find the first decision node, yes?
And how do I proceed if I've found a decision node ?
