Reinforcement Learning from Denoising Feedback

arXiv:2605.25638v2 Announce Type: replace-cross Abstract: Policy loss estimation remains a fundamental and long-standing challenge in reinforcement learning (RL) for diffusion language models (DLMs). We introduce Reinforcement Learning from Denoising Feedback (RLDF), a novel training paradigm that leverages feedback obtained from…

RePo: Language Models with Context Re-Positioning

arXiv:2512.14391v3 Announce Type: replace Abstract: In-context learning is fundamental to modern Large Language Models (LLMs); however, prevailing architectures impose a rigid and fixed contextual structure by assigning linear or constant positional indices. The rigid position information poses the full burden…

On the conditional equivalence of phase retrieval algorithms

arXiv:2606.07257v1 Announce Type: cross Abstract: Phase retrieval – recovering a complex-valued field from intensity measurements – is typically solved using variants of the Gerchberg-Saxton (GS) algorithm, understood as alternating projections between measurement planes. Meanwhile, modern computational imaging increasingly relies on…
