New methods improve Laplace approximation for neural network uncertainty

Researchers have developed new methods for approximating the Laplace approximation in deep neural networks, addressing the computational challenges of inverting large Hessian matrices. The proposed Gradient-Laplace and Greedy-Laplace methods offer principled ways to select parameters for sub-network approximations, aiming to reduce the underestimation of predictive variance inherent in existing heuristic approaches. Theoretical analysis and numerical studies suggest these new methods provide stronger optimality guarantees and outperform current benchmarks. AI
