Richer Bayesian Last Layers with Subsampled NTK Features

Sergio Calvo-Ordoñez, Jonathan Plenk, Richard Bergna +4

Bayesian Last Layers (BLLs) provide a convenient and computationally efficient way to estimate uncertainty in neural networks. However, they underestimate epistemic uncertainty bec…

A Gaussian Process View on Observation Noise and Initialization in Wide Neural Networks

Sergio Calvo-Ordoñez, Jonathan Plenk, Richard Bergna +4

Performing gradient descent in a wide neural network is equivalent to computing the posterior mean of a Gaussian Process with the Neural Tangent Kernel (NTK-GP), for a specific pri…

Uncertainty Modeling in Graph Neural Networks via Stochastic Differential Equations

Richard Bergna, Sergio Calvo-Ordoñez, Felix L. Opolka +2

We propose a novel Stochastic Differential Equation (SDE) framework to address the problem of learning uncertainty-aware representations for graph-structured data. While Graph Neur…

Graph Neural Stochastic Differential Equations

Richard Bergna, Felix Opolka, Pietro Liò +1

We present a novel model Graph Neural Stochastic Differential Equations (Graph Neural SDEs). This technique enhances the Graph Neural Ordinary Differential Equations (Graph Neural…
