Evidential Uncertainty Probes for Graph Neural Networks

AISTATS 2025poster

Accurate quantification of both aleatoric and epistemic uncertainties is essential when deploying Graph Neural Networks (GNNs) in high-stakes applications such as drug discovery and financial fraud detection, where reliable predictions are critical. Although Evidential Deep Learning (EDL) efficientl…

Noisy Low-Rank Matrix Completion via Transformed $L_1$ Regularization and its Theoretical Properties

AISTATS 2025poster

This paper focuses on recovering an underlying matrix from its noisy partial entries, a problem commonly known as matrix completion. We delve into the investigation of a non-convex regularization, referred to as transformed $L_1$ (TL1), which interpolates between the rank and the nuclear norm of mat…

Improvements on Uncertainty Quantification for Node Classification via Distance Based Regularization

NeurIPS 2023poster

Deep neural networks have achieved significant success in the last decades, but they are not well-calibrated and often produce unreliable predictions. A large number of literature relies on uncertainty quantification to evaluate the reliability of a learning model, which is particularly important fo…

Non-Convex Approaches for Low-Rank Tensor Completion under Tubal Sampling

ICASSP 2023accepted

Tensor completion is an important problem in modern data analysis. In this work, we investigate a specific sampling strategy, referred to as tubal sampling. We propose two novel non-convex tensor completion frameworks that are easy to implement, named tensor L <inf xmlns:mml="http://www.w3.org/1998/…
