DLTM Sampling

[mlnpapez]

I reproduced the results from your paper by running train_hclt.py on the MNIST dataset (achieving 1.21 bpd); however, after using backward with the DLTM model, I received the following output:

Are you going to add backward also to PIC?

Many thanks.

Hi, many thanks for playing with the code! The backward pass will not be implemented in PICs, as sampling from those energy-based-like neural nets is not straightforward and requires approximate techniques.
