PyTorch Conference Europe 2026

Uncertainty quantification is becoming more and more important as neural networks are used for increasingly critical tasks. Bayesian neural networks (BNNs) inherently provide a measure of their own uncertainty, but can be either hard to implement or inflexible if one uses common frameworks. In this session I discuss how to efficiently implement BNNs using Variational Inference within PyTorch and present torch_blue, a light-weight open source library that implements these methods with the goal of being easy to pick up, yet flexible enough for research on BNNs.
