Early successes in programming digital computers to exhibit simple forms of intelligent behavior, coupled with the belief that intelligent activities differ only in their degree of complexity, have led to the conviction that the information processing underlying any cognitive performance can be formulated in a program and thus simulated on a digital computer. Attempts to simulate cognitive processes on computers have, however, run into greater difficulties than anticipated. An examination ...

17 NOV 1965

Authors: E. A. HUBER; ELECTRONIC DEFENSE LABS SYLVANIA ELECTRONIC SYSTEMS-WEST MOUNTAIN VIEW CALIF

Network synthesis and transfer-function estimation are considered as parameter-estimation problems. Particular emphasis is given to the synthesis of linear electrical networks. To minimize the desired error measure, iterative gradient techniques are used to adjust the parameters automatically. Constraint equations to insure physical realizability are handled by means of Carroll's nonlinear programming technique. This technique transforms the minimization-with-constraints problem into an unconstrained minimization problem. The result is an automatic procedure which ...
