In the probability theory, there are two principles associated with entropy: the principle of maximum entropy and the principle of minimum cross-entropy. At very beginning we notice that there are two types of entropy, however there are more in stock. First of all, let us emphasize that neither the principle of maximum entropy nor the principle of minimum cross-entropy are theorems, they are only principles of statistical inference. This is very similar to philosophical doctrine. However, these doctrines certainly have mathematical implications. So we have two different types of entropy: entropy and cross-entropy.
