We introduce ArrowFlow, a machine learning architecture that operates entirely in the space of permutations. Its computational units are ranking filters, learned orderings that compare inputs via Spearman’s footrule distance and update through permutation-matrix accumulation, a non-gradient rule rooted in displacement evidence. Layers compose hierarchically: each layer’s output ranking becomes the next layer’s input, enabling deep ordinal representation learning without any floating-point parameters in the core computation. We connect the architecture to Arrow’s impossibility theorem, showing that violations […]

arXiv:2409.20412v2 Announce Type: replace-cross Abstract: Understanding the dose-response relation between a continuous treatment and the outcome for an individual can greatly drive decision-making, particularly in areas like personalized drug dosing and personalized healthcare interventions. Point estimates are often insufficient in these high-risk environments, highlighting the need for uncertainty quantification to support informed decisions. Conformal prediction, a distribution-free and model-agnostic method for uncertainty quantification, has seen limited application in continuous treatments or dose-response models. To address this gap, we […]

The current AI conference acceptance culture feels like it leaves little room for the kind of spark we once cherished in research (at least in my own experience). It seems to run on tons of evaluations to let reviewers believe solid, often far beyond the level of interest that can be realistically sustained for any single project, and almost nobody will verify them again. submitted by /u/NuoJohnChen [link] [comments]

arXiv:2603.25934v1 Announce Type: cross Abstract: In this work, we investigate how to develop sharp concentration inequalities for sub-Weibull random variables, including sub-Gaussian and sub-exponential distributions. Although the random variables may not be sub-Guassian, the tail probability around the origin behaves as if they were sub-Gaussian, and the tail probability decays align with the Orlicz $Psi_alpha$-tail elsewhere. Specifically, for independent and identically distributed (i.i.d.) ${X_i}_{i=1}^n$ with finite Orlicz norm $|X|_{Psi_alpha}$, our theory unveils that there is an interesting phase […]

arXiv:2601.08871v1 Announce Type: new Abstract: Balancing dialogue, music, and sound effects with accompanying video is crucial for immersive storytelling, yet current audio mixing workflows remain largely manual and labor-intensive. While recent advancements have introduced the visually guided acoustic highlighting task, which implicitly rebalances audio sources using multimodal guidance, it remains unclear which visual aspects are most effective as conditioning signals.We address this gap through a systematic study of whether deep video understanding improves audio remixing. Using textual descriptions […]

Reinforcement Learning (RL) offers a powerful framework for optimizing dynamic treatment regimes (DTRs). However, clinical RL is fundamentally bottlenecked by reward engineering: the challenge of defining signals that safely and effectively guide policy learning in complex, sparse offline environments. Existing approaches often rely on manual heuristics that fail to generalize across diverse pathologies. To address this, we propose an automated pipeline leveraging Large Language Models (LLMs) for offline reward design and verification. We formulate the reward function using […]
