Walsh Hadamard Agreement & Disagreement for the iterated system HD

Image
  This interactive sketch explores how a binary diagonal matrix D interacts with the Walsh–Hadamard mixing matrix H.  Each entry of D can be flipped between +1 and -1, dividing the nodes into two groups.  The code visualizes two derived operators:  ●​ X = HD + DH  ●​ Y = HD - DH  These have a surprisingly clean interpretation:  ●​ X keeps interactions between nodes with the same sign (“agreement”).  ●​ Y keeps interactions between nodes with opposite signs (“disagreement”). Because the Walsh–Hadamard matrix contains only ±1 entries, the resulting matrix values become simple:  ●​ reinforcement: +2  ●​ cancellation: 0  ●​ opposite reinforcement: -2  The graph views make this intuitive: ●​ The graph of X splits into same-sign clusters.  ●​ The graph of Y becomes a bipartite interaction graph between opposite-sign groups.  As entries of D are flipped, the system transitions between:  ●​ uniform structure (all signs e...
