This report summarizes theoretical, applied, and experimental studies in the areas of computational principles in complex intelligent systems, cybernetics, multivalued logic, and the mechanization of cognitive processes. This work is summarized under the following topic headings: properties of complex dynamic systems; computers and the language problem; a conceptual framework for the study of linguistics; axiomatics of self-reproduction; an automatic stochastic predictor and related processes; automata theory; a method for analyzing complex systems; cascaded computational networks; mathematical modeling of interactions in neurons and nets; an organism with a multilevel goal structure and heterarchic competitive control of its overt behavior; search and evaluation of significant event sequences in automated speech analysis; microscopic physics of information transducers; a visual image processor; tectal organization of ambystoma tigrinum; a display technique for neurophysiological data; speech analysis using series expansions; an approach to the elimination of free response distortion of an electrical network; adaptive sampling of speech; speech synthesis; and endocrine modeling.
