Maybe it doesn't make sense for Surprise to be 1 when the probability is 0.

@AAA-tc1uh

2 жыл бұрын

@@statquest I would expect a deeper answer than that, as the [0,1] range can be scaled with any constant to give any large-enough surprise value to probability 0. It's just that the function would be linear now.

@statquest

2 жыл бұрын

@@AAA-tc1uh Well, then you're stuck with the figuring out what that constant should be. Infinity? But that kind of opens another can of worms because anything times infinity is infinity. Thus, another advantage of using the log function is that the limit as x goes go zero is -infinity.

@AAA-tc1uh

2 жыл бұрын

@@statquest Sure, I understand, but my rebuttal would be: we already use the [0,1] range for the probability distribution with 0="would never happen" and 1="always happens" (not entirely correct, I know, e.g. continuous distributions) so the same way we could treat Surprise value of 0 as "no surprise at all", and 1 as "maximum surprise". And we have a nice, well-behaved range with no infinities or undefined behavior. Skimming Shannon's original paper I see he argues for the use of the logarithmic function in the opening paragraphs but never provides real deep reason other than convenience and and practicality in engineering usage (another point for the linear function suggested above). Edit: the real reason is the characterization of such function, see en.wikipedia.org/wiki/Entropy_(information_theory)#Characterization, which is apparently only satisfied by entropy function in this form, using logarithms, as proved by Shannon.
