    Inference of high-dimensional grammars is discussed. Specifically, techniques for inferring tree grammars are briefly presented. The problem of inferring a stochastic grammar to model the behavior of an information source is also introduced and techniques for carrying out the inference process are presented for a class of stochastic finite-state and context-free grammars. The possible practical ap... View full abstract»

  • An Optimal Control Methodology for Analyzing the Effects of Display Parameters on Performance and Workload in Manual Flight Control

    Publication Year: 1975, Page(s):423 - 430
    Cited by:  Papers (9)

    An approach to the analysis of the effects of display parameters on manual control based on an optimal control model of the human operator and a related model for task interference is presented. The methodology allows one to predict the effects of changes in display variables on both performance and attentional demand or workload. The methodology is applied to vertical situation displays for STOL ... View full abstract»

  • A Probabilistic Hypothesis for the Prediction of Visual Fixations

    Publication Year: 1975, Page(s):431 - 437
    Cited by:  Papers (3)

    A hypothesis is proposed that predicts regions where fixations are most likely to occur on a visual pattern viewed by a human test subject. A scheme is developed for evaluating a fixation probability density function for any given pattern, based on an assumed fixation probability density function for a pattern consisting of a single dot. Predictions of the hypothesis agree with experimental data a... View full abstract»

  • A State-Space Model for the Student Population in an Educational System

    Publication Year: 1975, Page(s):437 - 440
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (915 KB)

    A stochastic approximation method is presented for determining the parameters of a stochastic state-space model for the student enrollment vector in an educational system. As an example, the parameters of such a model are derived for the student population in the Faculty of Engineering of McMaster University, Hamilton, Ont., Canada. View full abstract»

  • Modeling a Hospital Organization

    Publication Year: 1975, Page(s):441 - 446
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1679 KB)

    A multidimensional input-output model of a hospital's components is developed which, because it tracks the flows of people, materials, and services, can be used for long-range planning and resource allocation, and dynamic simulation of the hospital. The model also allows the determination of shadow prices, and hence, the profitability of the various hospital components. View full abstract»

  • Difference Detection, Tradeoffs Between Detection Probability and Processing Complexity

    Publication Year: 1975, Page(s):446 - 452
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1704 KB)

    The detection of a difference between two n-dimensional vectors based on a noisy measurement of each vector is important for surveillance, quality control, motion detection, and other applications. Because of cost or complexity, an arbitrary reduction from n to p dimensions may be required before measurements are performed. Using a Gaussian noise assumption, the tradeoffs between detection probabi... View full abstract»

  • Optimal Control of Unreliable Dynamic Systems with Discrete Time Inspections

    Publication Year: 1975, Page(s):452 - 456
    Cited by:  Papers (1)

    The optimal control of unreliable dynamic systems where the mode (working or failed) is continuously inspected or monitored has received attention in the past. We consider the problem where instead of continuous inspection we have either no inspection or inspection at discrete time instants. The optimal feedback control is derived for the case where the system has no renewable capabilities. The ca... View full abstract»

    Social scientists are continually confronted with the problem of formulating models which describe how individuals make choices among alternative courses of action with uncertain consequences. Economists have developed a class of models which seem to deal particularly well with problems of this type. These models employ the ``expected utility theorem'' of von Neumann and Morgenstern and, for reaso... View full abstract»

  • Estimation of a Probability Density Function of Very Many Variables

    Publication Year: 1975, Page(s):463 - 466
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1014 KB)

    The problem of estimating an unknown probability density function from a sequence of samples is well known in pattern classification and many other problems. We approximate the unknown density function by a multivariable spline that is constructed from the histogram of samples. This spline function is expressed as a sum of combinatorially many terms. To assess these numerous terms, the technique o... View full abstract»

  • Value of Information in Conflictual Situations Two Simple Examples

    Publication Year: 1975, Page(s):466 - 470
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1566 KB)

    In conflictual situations where two (or more) rational and intelligent players make interdependent decisions to optimize their own payoffs, decisions are often made on the basis of some critical information as well as on what each player anticipates that the other player(s) will do. How much is the critical information worth to a particular player? How much more is the same information worth to th... View full abstract»

  • On Pattern Recognition and Quality Control

    The application of pattern recognition to quality control is shown. The well-known methodology of conventional quality control is described briefly to illustrate the philosophy of quality measurement. The advantages of adopting the pattern classification approach in quality control (or quality assurance) include on-line quality monitoring without much alteration of existing conventional systems, i...

    A method of detecting pits, peaks, ridges, and ravines on a digital array of terrain elevation data is described. The methods used are based on algorithms designed to detect bright and dark spots or streaks in pictures. View full abstract»
