Hey cshenton

you should be able to learn the likelihood scale

have a look at

> Hello, I usually worked with Full-bayesian approach but started to learn Edward for large dataset analysis (for VI). I just tested with a simple model (y\_i ~ N(mu, sigma)) where mu~N(0, 1.5) and sigma ~ Inv-Gamma(1,1). When I run klqp, the parameters are not identified (differs a lot whenever run). (1) Is there anything wrong that I did? (2) This example works well on ADVI (Stan). But, still I think klqp works well with this example. (though I guess the two are different) (3) How to monit…
