Aggregate posterior
WebThis is called the variational lower bound or evidence lower bound (ELBO). But I think what we're actually trying to maximize is the log-likelihood of our data: log p θ ( x) = L ( x, θ, ϕ) + K L [ q ϕ ( z x) p θ ( z x)] There are a few things I'm unsure about, in increasing order of difficulty. For the actual loss function of a VAE ...
