VideoTIR: Accurate Understanding for Long Videos with Efficient Tool-Integrated Reasoning

Zhe Gao, Shiyu Shen, Taifeng Chai +7

Existing Multimodal Large Language Models (MLLMs) often suffer from hallucinations in long video understanding (LVU), primarily due to the imbalance between textual and visual toke…

Contrastive Heliophysical Image Pretraining for Solar Dynamics Observatory Records

Shiyu Shen, Zhe Gao, Taifeng Chai +2

Deep learning has revolutionized solar image analysis, yet most approaches train task-specific encoders from scratch or rely on natural-image pretraining that ignores the unique ch…

Preserving Domain Generalization in Fine-Tuning via Joint Parameter Selection

Bin Pan, Shiyu Shen, Zongbin Wang +2

Domain generalization seeks to develop models trained on a limited set of source domains that are capable of generalizing effectively to unseen target domains. While the predominan…

Domain Generalization Guided by Large-Scale Pre-Trained Priors

Zongbin Wang, Bin Pan, Shiyu Shen +2

Domain generalization (DG) aims to train a model from limited source domains, allowing it to generalize to unknown target domains. Typically, DG models only employ large-scale pre-…

Bayesian Domain Invariant Learning via Posterior Generalization of Parameter Distributions

Shiyu Shen, Bin Pan, Tianyang Shi +2

Domain invariant learning aims to learn models that extract invariant features over various training domains, resulting in better generalization to unseen target domains. Recently,…

Be Bayesian by Attachments to Catch More Uncertainty

Shiyu Shen, Bin Pan, Tianyang Shi +2

Bayesian Neural Networks (BNNs) have become one of the promising approaches for uncertainty estimation due to the solid theorical foundations. However, the performance of BNNs is a…
