Abstract : Research on electrochemical adaptive machines for use in automatic pattern recognition has been continued with the following notable results: (1) A variety of theoretical analyses have appeared showing a corresponding variety of convergent 'weight-change algorithms' for a single-layer linear decision function array, thus lending additional credance to the belief that intrinsic field-induced electrochemical processes which bring about effective 'weight changes' as previously described will result in a convergent adaptive process even though they may agree only qualitatively with the optimum (quantitative) weight changes called for by the various theories; (2) Research on dendritic growth processes was temporarily but almost completely curtailed pending design and construction of additional laboratory facilities found to be necessary to promote continuous circulation of electrolyte during the electrodeposition of metals from solution; (3) Through basic experiments with simple two-electrode cell, quantitative design data for a single-layer complex array has now been obtained, i.e., the electrodynamic response, transient charge-transfer and proper dendrite impedance for a trainable array of 'active/plastic' dipoles which feed (in parallel) a low-impedance detector circuit.
