I have a matrix of data I want to run NMF on. The range of values is from -13.1 to 13.4. What's the best way to prep this data for NMF? I've seen people just take all the negative values and make them 0 but that seems to me like it massively cripples the variance in the data. Would it make sense to just add the absolute minimum to each value in the matrix so that it ranges from 0 to 26 instead? Or rescale the data from 0 to 1?
