Machine Learning Basics (iii)--information, information entropy and information gain

}^NP (x_i) \log_2 p (x_i)The sum of the traversal multiplication can be calculated using the inner product entropy. Information entropy, which is used to measure the degree of disorder of information (the greater the entropy, the more disordered, equals 0 o'clock, means that all categories are the same, fully ordered) the properties of entropy: (1) non-negative, 0 ≤0 0 The Shannon entropy and the best partitioning characteristics of the computed data set Calculates the Shannon entropy of a data
