PhysioBench: A Unified Benchmark for Physiological Signal Question Answering

PhysioBench is a unified benchmark for physiological signal question answering that consolidates annotations from 22 public datasets into 61.4 million question‑answer pairs spanning 30 tasks. Each pair is linked to a specific signal segment and traceable to its source annotation. The benchmark evaluates 21 models—including large language models, vision‑language models, time‑series language models, and physiological signal foundation models—under three settings, revealing that no model consistently excels across all modalities and tasks, and that performance is sensitive to question wording.

ZYT-World: A Real-Time Controllable World Model for Closed-Loop Autonomous-Driving Simulation

ZYT-World is a real‑time, controllable world model designed for closed‑loop autonomous‑driving simulation. It generates a full fisheye‑pinhole camera rig at native resolution, using Plucker adapters for camera geometry, ego‑motion adaptive layer normalization for motion control, and a lightweight pixel‑aligned layout to condition traffic participants. The model achieves high fidelity to a 40‑step teacher while being over 100 times faster, and includes an implicit‑memory module that preserves place‑specific evidence for long‑horizon stability.

HERMES: A Holistic End-to-End Risk-Aware Multimodal Embodied System with Vision-Language Models for Long-Tail Autonomous Driving

HERMES is a holistic end‑to‑end multimodal driving framework that incorporates long‑tail semantic knowledge into trajectory planning for autonomous vehicles. It uses a foundation‑model‑assisted annotation pipeline to build Long‑Tail Scene Context and Long‑Tail Planning Context, capturing hazard‑centric scene information, maneuver intent, and risk‑aware guidance. A Tri‑Modal Driving Module then fuses multi‑view visual observations, historical ego‑motion, and long‑tail semantic instructions to generate intent‑ and risk‑aware trajectories, achieving consistent performance gains on a large‑scale real‑world long‑tail driving benchmark.
