Resolves the first todo in #77. Also includes a simple change with which we can index 1D variable arrays with integers (instead of length 1 tuples).
Currently a lot of time is spent on graph construction (adding factors and constructing factor wirings) since PGMax is not making use of any of the structures present in an RBM.
In the future, to improve usability, it would be helpful to:
Separately, it would be helpful to introduce a pure functional interface so that we can leverage functionalities like
vmap
in JAX (which would allow us to parallelize sampling multiple digits in this use case). Connected to #68See below for some example samples
