New LL-HMC method makes uncertainty estimation in deep neural networks more feasible

Researchers have developed a new method called Last Layer Hamiltonian Monte Carlo (LL-HMC) to make uncertainty estimation in deep neural networks more computationally feasible. Traditional Hamiltonian Monte Carlo (HMC) is effective but too resource-intensive for large datasets and complex networks. LL-HMC restricts the sampling process to the final layer of a deep neural network, significantly reducing computational requirements. Experiments on real-world video datasets for driver action and intention recognition showed that LL-HMC achieves competitive performance in classification and out-of-distribution detection, with additional sampled parameters improving OOD detection.

    Last Layer Hamiltonian Monte Carlo

    arXiv:2507.08905v2 Announce Type: replace-cross Abstract: We explore the use of Hamiltonian Monte Carlo (HMC) sampling as a probabilistic last layer approach for deep neural networks (DNNs). While HMC is widely regarded as a gold standard for uncertainty estimation, the computati…
