Changing regularization, II
Today I went back to trying to understand the solution when using the original regularization. While doing so it occurred to me that if I use a slightly different regularization, I can get a closed-form solution for the feedforward connectivity $Z$, and without most (though not all) of the problems I was having in my…

These are my notes from early January on Kondor et al.’s Multiresolution Matrix Factorization from 2014. This was a conference paper and the exposition was a bit terse in places, so below I try to fill in some of the details I thought were either missing or confusing. Motivating MMF We will be interested in…
