comment Is there a relationship between Entropy of a fininte distrete probability distribution and the squre sum of the values of probability mass function of that distribution?
@ R W, first off, thanks a lot for the very informative reply! But I still have one more question, what do you mean by "naturally defined infinitesimal limits "? do you mean n go to infinite?

and I think for the case n = 2, it is true.

comment Do the Eigenvectors find by use PCA on a set of data point, a good replacement for Random Projection when I later on use L1Magic to reconstruct the sparse vector?
@Steve Hi Steve I changed my question a little, hope than will help.
