Researchers have developed a new Bayesian Learning Rule (BLR) that extends beyond the limitations of Kullback-Leibler divergence (KLD) geometry. This generalized BLR utilizes mixed-space Bregman or Fenchel-Young discrepancies, enabling additive information-geometric optimization algorithms. The new approach allows for the derivation of generalized maximum-entropy families and canonical gradient updates, which can lead to algorithms not possible with the classical KL-based BLR. Experiments on CIFAR-100 demonstrate that this generalized BLR can produce controllable support and heavy-tailed q-Gaussian posteriors with competitive performance. AI
