A new paper introduces two novel methods, Gradient-Laplace and Greedy-Laplace, for approximating Hessian matrices in deep neural networks. These methods aim to improve uncertainty quantification by addressing the computational challenges of the full Laplace approximation. The research demonstrates that existing sub-network Laplace approximations tend to underestimate predictive variance, and the proposed methods offer theoretical guarantees for optimality and improved performance over existing heuristic approaches.
