Info Processing at the Edge of Chaos
Info Processing = Info Storage + Info Transmission {Signalling}
CA Cell Cooperation <=> Can affect one another’s state
Mutal Information: Correlation between 2 cells
I(C1,C2) = H(C1) + H(C2) - H(C1,C2)
H(Cell) = Entropy of Cell values over time
H(Cell1, Cell2) = Entropy of value pairs over time
H(C1) high => periodic with long loops or chaotic
low => periodic with short loops or static
H(C1,C2) high => little correlation between C1 & C2
low => high correlation between C1 & C2 {Signalling}
I(C1,C2) high <=> frequently changing C1 & C2 {high H(C1) & H(C2)}
+ high correlation {low H(C1,C2)}
=> High Information Processing!
