From Pareto to Preference: Personalized Test-Time Scaling via Amortized Agentic Policy Discovery

Xinglin Wang, Zishen Liu, Tong Zheng وآخرون · 2026

Test-time scaling (TTS) improves the reasoning capabilities of large language models by allocating additional inference computation. Existing approaches to improving TTS efficiency largely optimize accuracy against one resource dimension at a time, advancing either the accuracy--cost or accuracy--latency Pareto frontie …

UniSkill: Learning Actor-Aligned Skill Proposals for an Evolving Policy

Yifei Lu, Cheng Liu, Dianzhi Yu وآخرون · 2026

Large language model agents can improve across tasks by retaining reusable skills distilled from prior interactions. Recent work jointly optimizes task execution and skill extraction, enabling the policy and skillbank to co-evolve. However, as the actor continues learning, rewarding skill proposals through their reuse …

Your Temporal Link Predictor Is Blind to Who Is Active: A Missing Factor That Transfers Across Models

Ji Zhang, Zixin Liu, Yiran Ding وآخرون · 2026

An interaction has two parts: someone decides to act, and then chooses whom to act on. Temporal link prediction has concentrated on the second, and we show that it is blind to the first by construction: a standard negative keeps the real source and swaps the destination, and we prove that this cancels the source's acti …

GlassGuard: Verified Glass Plane Mapping for Robot Navigation

Hanwen Guo, Zhengzhi Lin, Yusen Xie وآخرون · 2026

Transparent and specular surfaces pose a serious challenge to LiDAR-based SLAM and navigation because laser returns may pass through glass, leaving collision boundaries absent from the map. Prior work attempts to reconstruct the missing surfaces, but inaccurate obstacle placement can create the opposite failure: contam …

Map2Route: Benchmarking Compositional Language-Grounded Route Planning over Semantic Maps

Muyi Bao, Hang Xu, Jingfan Tang وآخرون · 2026

We introduce Map2Route, a human-curated benchmark for compositional language-grounded route planning over pre-built semantic maps. Map2Route contains 1,000 episodes across 40 scenes, where instructions use relational, comparative, and nested descriptions to identify route-relevant objects and regions, while specifying …
