Upper Bounds on the Generalization Error of Deep Learning Models via Local Robustness and Stability
Researchers are developing new methods to improve the reliability and understanding of deep learning models. One paper introduces Calibrated Variance Propagation (CVP) to provide accurate uncertainty estimates for transformers and CNNs at a fraction of the computational cost of traditional methods. Another study proposes tighter generalization bounds by considering local robustness and stability within input space sub-regions, showing improved estimates on ImageNet. A third contribution explores Bayesian principles to understand generalization in deep learning, offering new frameworks for uncertainty estimation and theoretical connections between diversity, smoothness, and stochasticity.
