Normal factor graphs: a diagrammatic approach to linear algebra
Ali Al-Bashabsheh, Yongyi Mao, Pascal O. Vontobel · 2016
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.
