Normal Factor Graphs: A Diagrammatic Approach to Linear Algebra
arXiv:1102.5755 · doi:10.1109/ISIT.2011.6033944
Abstract
Inspired by some new advances on normal factor graphs (NFGs), we introduce NFGs as a simple and intuitive diagrammatic approach towards encoding some concepts from linear algebra. We illustrate with examples the workings of such an approach and settle a conjecture of Peterson on the Pfaffian.
