Tele-Traversability: Rethinking Traversability for Teleoperated Ground Robots in Terrain Navigation

Teleoperation, a human-in-the-loop control scheme, allows a human operator to remotely command and guide a mobile robot to navigate in off-road environments, yet fluent and user-friendly tele-navigation requires an alignment of traversability evaluation between human and robot. In the teleoperation system, the human op...

Highlight-Then-Summarize: Learning to Compress Evidence for Long-Context Understanding

Long-context understanding requires large language models (LLMs) to reason over lengthy documents, conversations, and code, yet task-relevant evidence is often sparse and scattered amid substantial irrelevant and redundant content. We propose Highlight-Then-Summarize (H2S), a compress-then-reason paradigm that first id...

Implicit Manipulation for Skill Selection in LLM Agents with Semantic Matching

This work identifies a new implicit attack surface for skill selection: even when the user prompt and skill description appear benign in isolation, their semantic relationship can still be strategically shaped to favor an attacker-chosen skill.

Collective Communication for Distributed LLM Systems: Planning, Runtime Adaptation, and Computation Coordination

This paper presents a tutorial-style, collective-centric taxonomy for collective communication, which organizes recent advances into three layers: communication planning, which generates topology-aware collective schedules; communication execution and adaptation, which maps these schedules onto GPU runtimes and hardwar...
