Automated Trajectory Evaluation for Mobile Agents via Step-Level Consequence Reasoning and Aggregation

Evaluating language-guided mobile agents has recently shifted from rule-based to model-based approaches to achieve scalable and automated assessments. However, existing holistic evaluation paradigms process entire trajectories at once, leading to substantial context overload. Moreover, they primarily focus on task comp...

EdgeMem: LLM-Free Agent Memory Construction and Retrieval via Evidence-Preserving Multi-Anchor Hypergraph

Agent memory allows LLM agents to use earlier interactions when answering new queries. Existing methods often compress interaction histories into summaries or other LLM-generated representations. Repeated generation adds cost and can discard answer-bearing details before the system knows what a future query will requir...

InstructVVT: Instruction-Driven Video Virtual Try-On without Auxiliary Spatial Priors

InstructVVT is proposed, an instruction-driven and reference-guided video virtual try-on framework based on a Diffusion Transformer that operates without inference-time spatial priors that outperforms state-of-the-art open-source methods in garment fidelity, structural preservation, and temporal consistency, despite re...

SeerGuard: A Safety Framework for Mobile GUI Agents via World Model Prediction

This paper introduces SeerGuard, a consequence-aware safety framework designed to mitigate risks through pre-execution instruction-level screening and action-level risk assessment, and constructs a unified safety-augmented world model (SAWM) via multi-task learning, integrating semantic next-state prediction with safet...
