Research was directed toward the development of a new class of pattern recognition equipment for rapid and automatic detection andor classification of spatio-temporal patterns. One restricted but key class of systems was emphasized--functionally, adaptable linear decision functions structurally, a homogeneous array of goldiron dipoles in nitric acid which feed, in parallel, a low-impedance detector circuit--and means for direct excitation of such arrays by patterns of incident light. Theory shows that such a system and some others can be trained through the agency of diffuse or global electrical shocks applied across the whole array immediately following each improper response in a training sequence and, thus, avoid the conventional requirements for detailed access, connecting, or internal structuring and programming. During this process the size and structure and, hence, function of the dendrites is gradually altered in excited regions through differential dendritic electrodeposition and dissolution. When perfected and extended, this type of bulk process and others like it should lead to pattern recognition machines reaching entirely new levels of packing density and versatility. Additional design data was acquired through a number of basic experiments and completed an experimental sixteen-element Linear Field-Trainable LIFT array was completed together with compatible pattern input, control, and monitoring equipment.
