Question about K-L term objective

[ZZdozeoff]

Thanks for your contribution, this novel VED form pretrained dialog model is very helpful ! After reading your reasearch, I have a question about K-L regularization term. Most variational generation in dialog models use CVAE objective, they have prior and posterior network and use K-L term $KL (q(z|c,r) || p(z|c) )$ But in your work, this posterior $q(z|c,r)$ is replaced by $q(z)$. May I ask why do you use this replacement ?
