Cog-Rethinker: Hierarchical Metacognitive Reinforcement Learning for LLM Reasoning

arXiv:2510.15979v1 Announce Type: new Abstract: Contemporary progress in large language models (LLMs) has revealed notable inferential capacities via reinforcement learning (RL) employing verifiable reward, facilitating the development of O1 and R1-like reasoning models. Directly training from base models with RL…

Prominence-Aware Artifact Detection and Dataset for Image Super-Resolution

arXiv:2510.16752v1 Announce Type: cross Abstract: Generative image super-resolution (SR) is rapidly advancing in visual quality and detail restoration. As the capacity of SR models expands, however, so does their tendency to produce artifacts: incorrect, visually disturbing details that reduce perceived…

Non-asymptotic error bounds for probability flow ODEs under weak log-concavity

arXiv:2510.17608v1 Announce Type: cross Abstract: Score-based generative modeling, implemented through probability flow ODEs, has shown impressive results in numerous practical settings. However, most convergence guarantees rely on restrictive regularity assumptions on the target distribution — such as strong log-concavity or…
