Interaction Locality in Hierarchical Recursive Reasoning
Researchers have introduced a new framework called "interaction locality" to measure how information flows within AI models during spatial reasoning tasks. This framework analyzes whether computations remain localized or cross semantic boundaries, applying it to hierarchical and recursive reasoning models like HRM and TRM. The study found that high-level states in these models tend to write information locally, which is then accumulated into broader structures through recursive updates, a pattern also observed in embodied 3D models at module boundaries.
