Geometric Autoencoder Priors for Bayesian Inversion: Learn First Observe Later

ICLR 2026poster

Uncertainty Quantification (UQ) is paramount for inference in engineering applications. A common inference task is to recover full-field information of physical systems from a small number of noisy observations, a usually highly ill-posed problem. Critically, engineering systems often have complicat…

Towards Robust Multimodal Open-set Test-time Adaptation via Adaptive Entropy-aware Optimization

ICLR 2025poster

Test-time adaptation (TTA) has demonstrated significant potential in addressing distribution shifts between training and testing data. Open-set test-time adaptation (OSTTA) aims to adapt a source pre-trained model online to an unlabeled target domain that contains unknown classes. This task becomes…

MultiOOD: Scaling Out-of-Distribution Detection for Multiple Modalities

NeurIPS 2024spotlight

Detecting out-of-distribution (OOD) samples is important for deploying machine learning models in safety-critical applications such as autonomous driving and robot-assisted surgery. Existing research has mainly focused on unimodal scenarios on image data. However, real-world applications are inheren…

SimMMDG: A Simple and Effective Framework for Multi-modal Domain Generalization

NeurIPS 2023poster

In real-world scenarios, achieving domain generalization (DG) presents significant challenges as models are required to generalize to unknown target distributions. Generalizing to unseen multi-modal distributions poses even greater difficulties due to the distinct properties exhibited by different m…
