Demo: A Material-Aware RF Digital Twin for mmWave Object Recognition with No Real-World Labels

Millimeter-wave (mmWave) radar perception is bottlenecked by training data: every room reflects mmWave differently, so models do not transfer and labeling radar in each new space is impractical. We demonstrate a material-aware RF digital twin for object recognition with no real radar labels. From a 3D scan the twin inf...

Latent-Action-Guided Video-Language Feature Learning for Surgical Instrument-Tissue Interaction Recognition

This work introduces \the authors', which compresses frame-to-frame changes into latent actions and predicts next-frame features during end-to-end video--language alignment and achieves competitive recognition with faster inference and smaller INT4 accuracy drops than V-JEPA2/2.1.

From Vision to Harvest: Benchmarking Vision-Language Models for Multi-Arm Robotic Fruit Harvesting

This work introduces the first comprehensive benchmark for evaluating pretrained Vision-Language Models on zero-shot multi-arm fruit harvesting planning and shows that frontier VLMs can generate effective multi-arm harvesting plans zero-shot, but a practical deployment remains limited by accurate 3D waypoint generation...

Toward Self-Adaptive Physical AI: Can LLM Agents Manage Long-Horizon Physical Tasks?

The results show that zero-shot LLM agents can achieve comparable management outcomes to RL agents under the same weather pattern and adapt more effectively than RL when evaluated under a shifted environment, highlighting a promising path toward self-adaptive physical AI agents.

Taming Update Drift in Asynchronous Federated Learning via Orthogonal Calibration

OrthoFL is proposed, an orthogonal calibration framework that decouples global and local learning progress to reduce interference and consistently outperforms state-of-the-art asynchronous baselines under various delay patterns and heterogeneity scenarios.
