Imagining Recovery: Inference-Time Counterfactual Realignment for Vision-Language-Action Models

Yanyan Zhang, Disheng Liu, Kai Ye +6

Vision-language-action (VLA) models have improved the flexibility and generality of robotic manipulation, yet they remain fragile to online disruptions, such as changes in task goa…

Test-Time Scaling in Reasoning LLMs: Inference Regimes, Evaluation, and Reproducibility

Mohsen Hariri, Weicong Chen, Nahal Shahini +11

Large language models can solve substantially harder reasoning problems with more inference-time compute. The term "test-time scaling," however, now covers diverse inference algori…

CausalRAG2: Hierarchical Causal Knowledge Graph Design for RAG

Nengbo Wang, Tuo Liang, Vikash Singh +6

Retrieval augmented generation (RAG) has enhanced large language models by enabling access to external knowledge, with graph-based RAG emerging as a powerful paradigm for structure…

Mid-Think: Training-Free Intermediate-Budget Reasoning via Token-Level Triggers

Wang Yang, Debargha Ganguly, Xinpeng Li +5

Hybrid reasoning language models are commonly controlled through high-level Think/No-think instructions to regulate reasoning behavior, yet we found that such mode switching is lar…

100-LongBench: Are de facto Long-Context Benchmarks Literally Evaluating Long-Context Ability?

Wang Yang, Hongye Jin, Shaochen Zhong +4

Long-context capability is considered one of the most important abilities of LLMs, as a truly long context-capable LLM enables users to effortlessly process many originally exhaust…

Longer Context, Deeper Thinking: Uncovering the Role of Long-Context Ability in Reasoning

Wang Yang, Zirui Liu, Hongye Jin +3

Recent language models exhibit strong reasoning capabilities, yet the influence of long-context capacity on reasoning remains underexplored. In this work, we hypothesize that curre…
