    In many mathematical and engineering problems the solution is simpler after a transformation has been applied. A general method is proposed to find suitable transformations for discrete data in information processing problems. The main feature of the method is random perturbation of the data subject to constraints which ensure that, in the transformed space, the problem is in some sense simpler an... View full abstract»

    The objects and methods of automatic feature extraction on binary patterns are briefly reviewed. An intuitive interpretation for geometric features is suggested whereby such a feature is conceived of as a cluster of component vectors in pattern space. A modified version of the Isodata or K-means clustering algorithm is applied to a set of patterns originally proposed by Block, Nilsson, and Duda, a... View full abstract»

    An automated sleep electroencephalogram (EEG) analyzer has been designed and tested in an effort to eliminate tedious and variable human interpretation of experimental EEG data. Data is presented to a hybrid computer from EEG tapes recorded during experimental studies in a human sleep laboratory. Special analog filters are used to identify specific transient waveforms in the EEG. Bandpass filters ... View full abstract»

  • Controlling the Functional Testing of an Operating System

    Publication Year: 1969 , Page(s): 284 - 290

    Functional testing of operating systems is in transition from a predominantly imprecise art to an increasingly precise science. The process that controls this testing is maturing correspondingly. The laissez-faire approach is giving way to a disciplined approach characterized by rigorous definition of the test plan, systematic control of the test effort, and objective quantitative measurement of t...

  • A Minimum Variance, Time Optimal, Control System Model of Human Lens Accommodation

    Cited by:  Papers (3)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2311 KB)  

    Experimental data relating ciliary nerve stimulation and lens motion are used to identify the open-loop plant dynamics of the lens accommodation system via a parameter identication variation of the Kalman filter equations. Using the resultant minimum variance plant model, experimental closed-loop responses of the human accommodative system are predicted by synthesizing the system closed-loop contr...

    A survey of current trends of systems engineering in the glass industry is presented. The central theme is that systems engineering is the technique through which the process of our time¿the information revolution exemplified by the digital computer¿is exerting its impact on the industry. Systems engineering is examined and basic concepts reviewed, and the production system is defined as a pyram... View full abstract»

  • System Identification with Threshold Measurements

    Publication Year: 1969 , Page(s): 313 - 321
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1912 KB)  

    A method has been developed to analyze systems which have threshold properties. The only information about the system response that is used in the analysis is whether or not this response exceeds a fixed threshold of unknown magnitude. There are many biological systems that fall into this category of systems, for example, the auditory system, the visual system, electrical stimulation of nerve cell... View full abstract»

    A new type of visual feature extracting network has been synthesized, and the response of the network has been simulated on a digital computer. This research has been done as a first step towards the realization of a recognizer of handwritten characters. The design of the network was suggested by biological systems, especially, the visual systems of cat and monkey. The network is composed of analo... View full abstract»

  • The Information Transfer Required in Regulatory Processes

    Cited by:  Papers (7)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1220 KB)  

    Several fundamental relations between regulation and informational quantities are given. These show that regulation is a phenomenon closely tied to the transinformation between the regulator and the system which might be called its opponent. Two basic types of regulators are distinguished. The first, error-controlled regulators, are shown to be essentially coding devices which operate by taking ad... View full abstract»

  • Decision Processes in the Adaptive Behavior of Human Controllers

    Cited by:  Papers (6)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2005 KB)  

    A decision algorithm which simulates the rapid adaptive behavior of human controllers following sudden changes in plant dynamics is developed. The control of a VTOL aircraft in hover following failure of the stability augmentation system is used as a specific example. The decision algorithm is based on the assumption that the human controller recognizes certain pattern features in the error/error-... View full abstract»

  • Use of Stochastic Automata for Parameter Self-Optimization with Multimodal Performance Criteria

    The application of stochastic automata to adaptive parameter optimization problems is considered. The fundamental problem is that of relating the concepts of automata theory and mathematical psychology learning theory to the usual notion of a performance index in a control system. Consideration is given to a number of possible automata structures, linear and nonlinear. One particular linear model ... View full abstract»

  • The Asymptotic Approach to Traffic Dynamics

    The asymptotic model of traffic dynamics presented is simple to employ and yields solutions that can be interpreted in terms of a continuous flow process. Although the asymptotic model is an approximation and has not been fully developed, the results that are now available are of such significance that one must question the feasibility of the determination of parameters for the various models by d...

  • On Playing Two-Person Zero-Sum Games against Nonminimax Players

    Results on a practical method for exploiting weakness in the play of an opponent in two-person zero-sum games are reported. Finite-state machines obtained by an evolutionary process are used to determine the move against a nonminimax opponent and achieve average payoffs significantly better than the value of the game.

    This correspondenice attempts to point out the invalidity of a convergesnce property asserted by R.W. McLaren (ibid., vol. SSC-2, pp. 109-114, December 1966) for a stochastic automaton model for learning systems. The error results from ani erronieous derivation of eq. (18) from eq. (17). View full abstract»
