It is well known that a rate-distortion-optimal source encoder's output generally doesn't match its source's distribution. This can make some analyses a pain in the neck. For example, say you …
Some Useful Multivariate Gaussian Information Quantities
Many information quantities for multivariate normal distributions have nice closed forms. Their essential parts usually reduce to logs of minor determinant quotients so they combine nicely. Here's a list of …
Combinatoral Iteration in Matlab
Often we need a to write a program that iterates over all combinations of k elements from some set (elements chosen without replacement). It isn't obvious how to efficiently …
Some Interaction Information Examples
Interaction information between three random variables has a much less immediate interpretation compared to other information quantities. This makes it more tricky to work with. An i.i. term I …
