arXiv:2604.04087v2 Announce Type: replace Abstract: 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.

The paper introduces a novel machine learning architecture that operates in the space of permutations, signaling an alternative approach to traditional floating-point-based models, emerging from ongoing research into more efficient and specialized AI paradigms.
This new architecture, ArrowFlow, could lead to more robust and explainable AI systems, particularly in ranking and ordering tasks, potentially broadening the applicability of machine learning to domains where traditional methods struggle.
The core computation of this deep ordinal representation learning system operates without floating-point parameters, which could lead to advancements in energy efficiency, data privacy through non-gradient updates rooted in displacement evidence, and new hardware optimizations for permutation-based AI.
