Begriffe

Stochastic bottleneck

Intermediate layer of VAEs where information is compressed into random variables following probability distributions, unlike the deterministic bottleneck of classical autoencoders.

Begriffe

Latent sampling

Process of sampling points in the latent space according to the distributions learned by the encoder, enabling the generation of diverse and realistic new data.

📖

Begriffe

VAE loss function

Composite objective function combining the reconstruction loss (typically mean squared error or binary cross-entropy) and the KL divergence regularization term.

📖

Begriffe

Stochastic regularization

Inherent mechanism in VAEs that prevents overfitting by forcing latent distributions to remain close to the prior distribution, ensuring a continuous and interpolable latent space.
