AdaGait: Domain-Adaptive Multi-Person Gait Authentication Using Commodity WiFi Devices

WiFi channel state information (CSI) enables privacy-preserving, device-free continuous authentication on commodity hardware. However, CSI is highly sensitive to room layout and walking routes. When several people walk at the same time, their signals overlap and create strong inter-person interference. Many existing ga...

Agentic AI-aided resource allocation for multi-task and multi-modal semantic communications

WirelessOpsAgent: A Benchmark and Agent Design for Action Assurance in Wireless Networks

Large language model (LLM) agents are emerging as planners for autonomous wireless network operations. Yet a task answer that is correct at proposal time can still be unsafe at execution time if supporting telemetry is stale or inconsistent. Existing benchmarks mainly evaluate task solving from fixed observations and l...

SuperSenseDoctor: A Multimodal and Contactless Agent for Health Tracking

The results demonstrate the feasibility of a stateful contactless sensing-to-action architecture for long-term home health monitoring and integrates sensing, temporal state, reasoning, and action into a unified and auditable loop.

Prior Directions: Why GUI Grounding Gets Locked in the Past

Vision-language models often use descriptions of earlier visual states to make decisions about the current scene. When the scene changes, stale language can redirect an otherwise correct visual judgment toward an outdated answer. We study this failure as visual lock-in in a controlled grounding setting where only the v...

VITAL-RAG: Invariance Race for Context Allocation in Coding Agents

VITAL-RAG is introduced, which organizes evidence by canonical code object, keeps one query-relevant companion only when it adds semantics not already represented, and renders selected evidence under per-object and global token budgets.
