Lowest entropy
Web28 jul. 2024 · Improve this question. The formula for cross entropy loss is this: − ∑ i y i ln ( y ^ i). My question is, what is the minimum and maximum value for cross entropy loss, given that there is a negative sign in front of the sum? For example: let's say ground truth values, y = [ 0, 1, 0] and the predicted y ^ = [ 0, 0, 1].

Web4 jan. 2024 · 1 Answer. Entropy is not quantification of amount of information. Entropy is quantification of surprise (or unpredictability) in the information. In your example, the top of node actually has less predictable information. It says that you will either see a male or a female, which is only somewhat helpful. On the other hand, once you move to a ... Web52. I know that entropy is the measure of randomness of a process/variable and it can be defined as follows. for a random variable X ∈ set A :- H ( X) = ∑ x i ∈ A − p ( x i) log ( p ( x i)). In the book on Entropy and Information Theory by MacKay, he provides this statement in Ch2. Entropy is maximized if p is uniform.
