Researchers have developed a new method for derandomizing PAC-Bayes generalization bounds, specifically for smooth loss functions. This approach aims to provide high-probability bounds for deterministic predictors by leveraging the smoothness properties of both the loss function and the predictor class. The framework allows for the control of generalization gaps using quantities derived from parameter Jacobians and Hessians, with applications to linear predictors and neural networks. A practical regularizer is also proposed, inspired by these theoretical quantities, and its behavior is demonstrated on the CIFAR-10 dataset using BatchNorm networks. AI
