"Dynamic perceptron". An outlook of computational dynamics

With respect to Rosenblatt linear perceptron, a classical limitation theorem demonstrated by Minsky-Papert is discussed. This theorem, "Ψ_One-in-a-box", ultimately concern the intrinsic "mathematical" limitations of parallel calculations in pattern recognition problems. We demonstrate a possible solution of this limitation problem by substituting the static definition of characteristic functions and of their domains in the "geometrical" perceptron, with their dynamic definition. This dynamics consists in the mutual redefinition of the characteristic function and of its domain depending on the matching with the input. We show an application of this "dynamic" perceptron scheme in particle tracks recognition in high energy physics. This algorithm has actually been used for real time automatic triggering of ADONE e⁺e^- storage ring (Frascati, Rome) to evaluate the neutron time-like electromagnetic form factor in the context of "Fenice" collaboration by Italian Institute of Nuclear Physics (INFN).
