arXiv:2606.25293v1 Announce Type: new Abstract: Positional encodings (PEs) are essential for Transformers. Yet designing effective PEs for non-Euclidean graphs remains challenging. Such encodings should ideally induce an Attention-Compatible Geometry for self-attention: not merely describing graph structure, but defining a geometry whose inner products reflect meaningful structural relatedness. To realize this geometry, we propose Communicability-Inspired Positional Encoding (CIPE), built from communicability, a measure between pairs of nodes that aggregates contributions from paths of all len
This paper addresses a fundamental challenge in applying Transformers to non-Euclidean graph data, a domain increasingly relevant for complex AI applications, signifying ongoing foundational research in AI architectures.
Effective positional encodings are critical for Transformer performance, and advancements in this area, particularly for graphs, will expand the capabilities and applicability of state-of-the-art AI models, impacting various downstream applications.
The proposal of Communicability-Inspired Positional Encoding (CIPE) introduces a new method for representing structural relationships in graphs for Transformers, potentially leading to more robust and powerful graph neural networks.
