Shannon Entropyextends toKL Divergence & Cross Entropy
KL divergence is relative entropy: entropy extended from one distribution to a pair.
KL Divergence & Cross Entropyapplied inVAE & ELBO
The regularizer in the ELBO is a KL divergence.
VAE & ELBOextends toScore Matching
From a likelihood bound for latent-variable models to objectives that learn the score directly.
Score Matchingextends toConditional Technique
Conditioning makes the score matching objective tractable.
Conditional Techniqueextends toProbability Flow ODE
Once the score is learned, the SDE can be replaced by an equivalent deterministic ODE.
VAE & ELBOcontrastLeWorldModel / SIGReg
Both learn latent representations: the VAE reconstructs observations, LeWorldModel predicts only in latent space and relies on SIGReg against collapse.
