the categorical model is non-parametric. do you know why?
my signal subgraph model from my PAMI paper is semi-parametric. do you know why?

A categorical model is nonparametric because it assumes no knowledge about the form of the data. The signal subgraph model is semiparametric because the joint distribution over all graphs and classes is parametric (at first glance it looks nonparametric because of the indexing, but these indices are actually a function of model parameters determined as a first step in this algorithm) and the classifier is a nonparametric argmax, over an index of classes, of the joint distributions calculated in the first step.
