TTVD: Towards a Geometric Framework for Test-Time Adaptation Based on Voronoi Diagram

ICLR 2025poster

Deep learning models often struggle with generalization when deploying on real-world data, due to the common distributional shift to the training data. Test-time adaptation (TTA) is an emerging scheme used at inference time to address this issue. In TTA, models are adapted online at the same time wh…

Continual Domain Adversarial Adaptation via Double-Head Discriminators

AISTATS 2024poster

Domain adversarial adaptation in a continual setting poses significant challenges due to the limitations of accessing previous source domain data. Despite extensive research in continual learning, adversarial adaptation cannot be effectively accomplished using only a small number of stored source do…

Progressive Voronoi Diagram Subdivision Enables Accurate Data-free Class-Incremental Learning

ICLR 2023poster

Data-free Class-incremental Learning (CIL) is a challenging problem because rehearsing data from previous phases is strictly prohibited, causing catastrophic forgetting of Deep Neural Networks (DNNs). In this paper, we present \emph{iVoro}, a novel framework derived from computational geometry. We f…

Improving uncertainty calibration of deep neural networks via truth discovery and geometric optimization

UAI 2021poster

Deep Neural Networks (DNNs), despite their tremendous success in recent years, could still cast doubts on their predictions due to the intrinsic uncertainty associated with their learning process. Ensemble techniques and post-hoc calibrations are two types of approaches that have individually shown…
