I have recently started learning about variational inference and had few confusions.

In case of VAE, it is said that the posterior distribution is intractable because the marginal likelihood is intractable.

My understanding as to why marginal likelihood is intractable:


In the above integration case, latent variable z is continuous. So, if we are to marginalize over z, we will be considering all values of this continuous random variable z. Considering ALL values means that we will be considering …
