Hierarchical Uncertainty Exploration via Feedforward Posterior Trees

NeurIPS 2024poster

When solving ill-posed inverse problems, one often desires to explore the space of potential solutions rather than be presented with a single plausible reconstruction. Valuable insights into these feasible solutions and their associated probabilities are embedded in the posterior distribution. Howev…

Uncertainty Visualization via Low-Dimensional Posterior Projections

CVPR 2024poster

In ill-posed inverse problems it is commonly desirable to obtain insight into the full spectrum of plausible solutions rather than extracting only a single reconstruction. Information about the plausible solutions and their likelihoods is encoded in the posterior distribution. However for high-dimen…

Uncertainty Quantification via Neural Posterior Principal Components

NeurIPS 2023poster

Uncertainty quantification is crucial for the deployment of image restoration models in safety-critical domains, like autonomous driving and biological imaging. To date, methods for uncertainty visualization have mainly focused on per-pixel estimates. Yet, a heatmap of per-pixel variances is typical…
