How do I adjust the anchor point of a CALayer, when Auto Layout is being used?
...f.otherView.transform = CGAffineTransformRotate(self.otherView.transform, M_PI/8.0);

What is “entropy and information gain”?
.... P(m)=9/14 and P(f)=5/14. According to the definition of entropy:
Entropy_before = - (5/14)*log2(5/14) - (9/14)*log2(9/14) = 0.9403
Next we compare it with the entropy computed after considering the split by looking at two child branches. In the left branch of ends-vowel=1, we have:
