WebSep 29, 2024 · Training β-VAE by Aggregating a Learned Gaussian Posterior with a Decoupled Decoder. The reconstruction loss and the Kullback-Leibler divergence (KLD) loss in a variational autoencoder (VAE) often play antagonistic roles, and tuning the weight of the KLD loss in -VAE to achieve a balance between the two losses is a tricky and dataset … Webwith open-set recognition through a natural mechanism based on the aggregate posterior in a single model. 1.1.2. Out-of-Distribution and Open Set Recognition The above-mentioned literature focused their efforts predominantly on addressing catas-trophic interference. Even though continual learning is the desideratum, the corresponding

WebThe aggregate posterior is defined as q ( z) = E p ∗ ( x) [ q ( z x)], and the cross-entropy C E ( q ( z) ‖ p ( z)) = E q ( z) [ − log p ( z)]. This form is easily obtained by writing out K L ( q ( z x) ‖ p ( z)) = E q ( z x) [ − log p ( z) + log q ( z x)] and simplifying on the LHS.
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.
