I’m trying to build a simple DPMM with binomial distributions as the component dists. However, even Metropolis’ sampling is extremely slow (only like 10draws/s max) with N=200 NUTS, ADVI are also extremely slow. Is there any reason such a simple model should take so long to sample? Here is the m…

Simple Dirichlet Process Binomial Mixture Model samples slow

I did notice that reducing N from 200 to 20, the sampling speed increases by 100X
Not sure why that would be either…
