In Python/numpy, the programming dimensionality can be evaluating with x.ndim, and the math dimensionality with x.shape (or x.size or len(x)). On the other hand, with a generative model one starts from assumptions about how the data are generated (the forward model), and then performs inference about the model given the data (the backward step).
