RelaxedOneHotCategorical in Edward


#1

I am using RelaxedOneHotCategorical in Edward model, similar to

logits = nn(..)
tau = Gamma(0.1, 0.5)
y_prob = RelaxedOneHotCategorical(tau, logits)

and use KLqp for inference, but my Loss is negative after few iterations. My question is

a) Is RelaxedOneHotCategorical supported in Edward
b) Is my usage correct?
c) Are there any issues with KLqp inference when using such a model?
