Entropic Auto-Encoding via Implicit Free-Energy Minimization
Researchers propose Entropic Autoencoders, a structural fix to a long-standing VAE failure mode where latent variables become unused during training. Rather than explicitly penalizing the prior, EAEs rely on reconstruction loss alone while an ensemble of encoders implicitly enforces entropy constraints through free-energy minimization. This shifts the optimization landscape to favor informative representations over decoder shortcuts. The approach addresses a core limitation that has constrained VAE utility in generative modeling and representation learning, potentially reopening the architecture's viability for tasks where posterior collapse currently forces practitioners toward alternatives like diffusion models.62
