Computational Mechanics

For a time I was interested in the theory of Computational Mechanics due to (among others) Crutchfield and Young. The following is a small document, largely notes on and a retelling of (with a small extension to contact processes and slightly different perspective) this paper by Shalizi and Moore. The discussion concerns using computational mechanics to frame the question of constructing good observables for complex systems.
