A Basic Notion in the Theory of Cognitive Systems

IN a previous communication1 a network was described which would resolve linear relations among continuous input signals. It was indicated that for times greater than the resolution time (for some intrinsic error criterion) this net could follow changing relations and thus, by means of other nets, one could observe the relations between relations and so on. The process described is essentially that of ascending a scale of logical types. To characterize this more generally, consider a binary time series y(t) of discrete time t. If this contains 2r2m structures of length it can be described by a logical function:
