What type of algorithm (or at least what general class of algorithm) is generating the model? I'm just curious because I'm wondering if the input data has to be linearly separable or if it has a limited number of classes(I think that the iris dataset is only linearly separable in one case)?

Looks like good old decision trees to me (with some discretization for continuous input values).

As skystorm notes, these are decision trees. We have a limit on the number of classes (it's in the hundreds). We'll increase this as we improve the algorithms.
