Induction and information gain
Did you know?
Webc. Figure 4.13 shows that entropy and the Gini index are both monotonously increasing on the range [0, 0.5] and they are both monotonously decreasing on the range [0.5, 1]. Is it possible that information gain and the gain in the Gini index favor different attributes? Explain. We see that in the figure the entropy and the Gini index are both monotonous … WebReading time: 40 minutes.
