- if we have probability for each value, how to see the value’s distribution? We can use histgram to see the possible pdf (probability density function) overall. Then using KDE (Kernel Density Estimation) to fit pdf. Reference as follows. https://jakevdp.github.io/blog/2013/12/01/kernel-density-estimation/
- Do you use random forest? If so, what’s entropy?
To measure the quality of a split: Gini impurity.
Entropy for the information gain. Need to explain it in detail.
