I have a sparse matrix of count data that I'm using as input to a neural network.

I know, usually, the input data should be normalized (e.g. via min-max scaling, $z$-score standardization, etc.). But for features that are counts, what is a good approach? Should I $\log_2(x+1)$ transform the data and then do a $z$-score standardization? Is there another better approach?
