Today I stumbled upon Holographic Reduced Representations (HRR). By chance, it ties nicely with the last AI-ish post and the part-hole paper.

HRRs are introduced by Tony Plate in this paper: Holographic Reduced Representations as well as this book, also by Plate: Holographic Reduced Representation: Distributed Representation for Cognitive Structures

HRRs are also used in this paper: Associative Long Short-Term Memory. (This is also the way I found them).

I’ll admit that right now I don’t understand HRRs at all. Hopefully this will get better over time.
