Riemannian Graph Tokenizer for Structural Knowledge Transfer
The Riemannian Graph Tokenizer (RGT) uses Riemannian geometry to bridge structural knowledge and quantized representations for cross-domain transfer in graph data. It defines a geometric vocabulary (trees, cycles, sequences), quantizes structures using a Riemannian quantizer with an RSTE, and employs a geometry-aligned decoder. This method enables consistent structural knowledge transfer across different graph domains.
