PRIMUS: Pretraining IMU Encoders with Multimodal Self-Supervision

arXiv:2411.15127v3 Announce Type: replace Abstract: Sensing human motions through Inertial Measurement Units (IMUs) embedded in personal devices has enabled significant applications in health and wellness. Labeled IMU data is scarce, however, unlabeled or weakly labeled IMU data can be used…

An Analytical Characterization of Sloppiness in Neural Networks: Insights from Linear Models

arXiv:2505.08915v2 Announce Type: replace Abstract: Recent experiments have shown that training trajectories of multiple deep neural networks with different architectures, optimization algorithms, hyper-parameter settings, and regularization methods evolve on a remarkably low-dimensional “hyper-ribbon-like” manifold in the space of probability distributions.…

Robustness of LLM-enabled vehicle trajectory prediction under data security threats

arXiv:2511.13753v1 Announce Type: new Abstract: The integration of large language models (LLMs) into automated driving systems has opened new possibilities for reasoning and decision-making by transforming complex driving contexts into language-understandable representations. Recent studies demonstrate that fine-tuned LLMs can accurately…

Adaptive Redundancy Regulation for Balanced Multimodal Information Refinement

arXiv:2511.13755v1 Announce Type: new Abstract: Multimodal learning aims to improve performance by leveraging data from multiple sources. During joint multimodal training, due to modality bias, the advantaged modality often dominates backpropagation, leading to imbalanced optimization. Existing methods still face two…
