CaT-Diff: Cascaded Text-enhanced Diffusion Model for Time-Series Imputation

AAAI 2026technical

Most state-of-the-art time series imputation methods can leverage textual information to improve imputation quality, but they often struggle because they fail to effectively filter noisy information from large language model (LLM) derived textual information. Some existing solutions only filter over

Low-Rank Test-Time Training for Pre-Trained Point Cloud Models

CVPR 2026

Test-time training (TTT) enhances the robustness of pretrained models to out-of-distribution (OOD) data through auxiliary self-supervised tasks, without requiring labeled samples. However, existing TTT methods predominantly rely on decoder-based auxiliary objectives, which suffer from inefficient ad

On-Device Realistic Test-Time Adaptation via Bias-Resistant Statistical Alignment

IJCAI 2026

Test-Time Adaptation (TTA) aims to adapt pretrained models to unseen test data, which is crucial for resource-constrained edge devices that must handle distribution shifts on the fly without human supervision. However, conventional TTA methods often fail in realistic scenarios characterized by conti

CVLUE: A New Benchmark Dataset for Chinese Vision-Language Understanding Evaluation

AAAI 2025technical

Despite the rapid development of Chinese vision-language models (VLMs), most existing Chinese vision-language (VL) datasets are constructed on Western-centric images from existing English VL datasets. The cultural bias in the images makes these datasets unsuitable for evaluating VLMs in Chinese cult…

CoreRec: A Counterfactual Correlation Inference for Next Set Recommendation

AAAI 2024technical

Next set recommendation aims to predict the items that are likely to be bought in the next purchase. Central to this endeavor is the task of capturing intra-set and cross-set correlations among items. However, the modeling of cross-set correlations poses challenges due to specific issues. Primarily,…
