    This is a speculative position paper on a very large-scale system which may be suitable as a national goal. The paper discusses some of the pros and cons of constructing a large free-standing city in the U.S. in this decade. It then illustrates the initiation of planning using basic graphical techniques.

    An approach is presented for planning a health care system on a regional basis. The major components of the process are embodied in four computerized models: a demographic model; a facilities-location model; a regional and local model of the interactions of physicians, patients, and facilities; and a model which uses dynamic programming to determine the best strategy to follow in sequentially alte...

    This is a survey of some illustrative mathematical and econometric models. Both purely theoretical and applied models are discussed, and the limits of their utilization indicated. The recent disturbances of the economy have raised questions about public policy and the kind of controls which might be implemented. The use of optimal control theory in economics and, in particular, its application to ... View full abstract»

    The approach described in this paper represents a substantive departure from the conventional quantitative techniques of system analysis. It has three main distinguishing features: 1) use of so-called ``linguistic'' variables in place of or in addition to numerical variables; 2) characterization of simple relations between variables by fuzzy conditional statements; and 3) characterization of compl...

    Great promise is shown by combining man and computers via interactive graphics to solve problems neither could solve alone. The behavior of man in this problem-solving combination must be studied just as any computer problem-solving system. The example problem studied is parameter estimation. After collecting observational data, a mathematical model of the data generation process is constructed wh... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1304 KB)

    We present a model of threshold learning that represents discrete one-dimensional learning processes by a continuous two-dimensional learning process. The model gives us an overall view of the learning dynamics of an expanded range of training procedures, and provides insight into the training of multidimensional linear pattern classifiers. In our model the expected performance is measured by lear... View full abstract»

    The use of a gradient search algorithm for the computation of the minimum of a function is well understood. In particular, in continuous time, the algorithm can be formulated as a differential equation whose equilibrium solution is a local minimum of the function. Khas'minskii has proposed using the continuous gradient algorithm with a white-noise driving term. He shows, using an argument on the c... View full abstract»

    An algorithm for classifying a data set into an initially unknown number of categories is presented. It is composed of procedure for selecting initial points, a mode estimation procedure, and a classification rule. An integer valued function is defined on the sample space and a gradient search technique is used for estimating its modes. A procedure for mode estimation in the case of an infinite da...

    This paper presents properties of several different algorithms suitable for multicategory classification of hand-printed alphanumeric characters. In the character reader the input patterns are generally composed of the template characters and their distorted ones. Using the template patterns, a nonparametric procedure is developed for determining linear discriminant functions. Furthermore, we prop... View full abstract»

    A trajectory optimization technique for multidimensional nonlinear processes is presented. Problems which are cast in a discrete-time mold are considered. The method is based on dynamic programming and employs a combination of the technique of functional approximation and the method of region-limiting strategies. The cost function at each stage is approximated by a quadratic polynomial in a region... View full abstract»

    Some gray-level manipulation techniques are described, the first of which involves changing the gray-level distribution within the picture. Thereafter a method for extracting relatively noise-free objects from a noisy background is described. The purpose of these techniques is to preprocess a textural scene for subsequent analysis or classification. The present state of the art of texture analysis... View full abstract»

    A learning model of fuzzy formal language is proposed and discussed. We continue training the learning machine by giving sets of sentences sequentially. As a result of parsing of the given teaching sentences, the learning machine reinforces fuzzy grades of membership of productions in an inherent fuzzy grammar of the machine. The convergence of the proposed model is considered, and it is shown tha... View full abstract»

  • A Heuristic Method for Finding Most Extrema of a Nonlinear Functional

    A heuristic search is described which has the aim of finding practically all the extrema of a given nonlinear functional. A standard unimodal descent algorithm is employed for finding individual extrema. This basic algorithm is applied repeatedly using various computed initial points and starting directions. Through the additional use of several learning cycles most of the available extrema can be... View full abstract»

    The performance of variable-structure stochastic automata in stationary random environments has been extensively studied for the case when the environment's response is 0 or 1 (P model). A method is suggested for extending the updating schemes known for the P model to the S model, where the environment's output can lie in the interval [0,1], and a class of optimal nonlinear schemes for the S model...
