  • Pattern systems and methodologies for multiparadigm analysis and design

    Creator:
    Knutson, Charles D.
    Abstract:
    In this research, we have captured, in pattern form, key elements of programming and design in four programming paradigms (imperative, object-oriented, functional and logical) as well as multiparadigm programming. These pattern sets have formed a foundation upon which we were able to build a deeper understanding of multiparadigm programming and...

  • Design and implementation of a reusable specialized view for the ViewBuilder environment

    Creator:
    Trognon, Hervé R.
    Abstract:
    Application supporting a Graphical User Interface (GUI) are difficult to create. Their inherent complexity, their interdependence with many other disciplines, and the inadequacy of the existing tools leave the programmer with too much to do. In particular, almost no help is provided to create application-specific code. Some visual formalisms such...

  • Selecting appropriate representations for learning from examples

    Creator:
    Flann, Nicholas S. and Dietterich, Thomas G.
    Abstract:
    The task of inductive learning from examples places constraints on the representation of training instances and concepts. These constraints are different from, and often incompatible with, the constraints placed on the representation by the performance task. This incompatibility explains why previous researchers have found it so difficult to construct good...

  • Varieties of operationality

    Creator:
    Dietterich, Thomas G. and Bennett, James S.
    Abstract:
    In recent papers on machine learning, the term 'operationalization' has been used to describe the purpose of the learning process. In particular, explanation-based learning systems are said to 'operationalize' the given target concept. Unfortunately, the exact meaning of this term has varied from one paper to another, and frequently the...

  • Error-correcting output codes : a general method for improving multiclass inductive learning programs

    Creator:
    Dietterich, Thomas G. and Bakiri, Ghulum
    Abstract:
    Multiclass learning problems involve finding a definition for an unknown function f(x) whose range is a discrete set containing k > 2 values (i.e., k "classes") . The definition is acquired by studying large collections of training examples of the form (xi, f(xi)) . Existing approaches to this problem include...

  • The test incorporation hypothesis and the weak methods

    Creator:
    Bennett, James S. and Dietterich, Thomas G.
    Abstract:
    Test incorporations are program transformations that improve the performance of generate-and-test procedures by moving information out of the "test" and into the "generator." The test information is said to be "incorporated" into the generator so that items produced by the generator are guaranteed to satisfy the incorporated test. This article...

  • Program transformation method in DataLab : transforming visual specifications of ADTs to imperative code

    Creator:
    Al-Mulhem, Muhammed and Lewis, Ted G.
    Abstract:
    This paper describes the program transformation method used in DataLab, a general-purpose system for the specification and synthesis of abstract data types (ADTs). We present a model for transforming visual specifications of ADTs to imperative code. This model includes two forms of internal representations: one for the ADTs visual specifications...

  • Probabilistic tracking and real-time assessment of physical systems

    Creator:
    Brittain, R. Wade
    Abstract:
    In order for long-range autonomous robots to be successful they must be able to maintain accurate information about their location, available resources, and the state of critical components. We propose here a methodology which incorporates traditional, sensor-based tracking methods with discrete probabilistic representations of system state. Further, we extend the...

  • A comparative study of ID3 and backpropagation for English text-to-speech mapping

    Creator:
    Dietterich, Thomas G., Hild, Hermann, and Bakiri, Ghulum
    Abstract:
    The performance of the error backpropagation (BP) and ID3 learning algorithms was compared on the task of mapping English text to phonemes and stresses. Under the distributed output code developed by Sejnowski and Rosenberg, it is shown that BP consistently out-performs 1D3 on this task by several percentage points. Three...

    Abstract:
    This paper describes the design and implementation of a graphical user interface for construction and evaluation of influence diagrams. Specifically, this paper documents the representation, display and mouse sensitivity of an influence diagram, and the selection facility subsystem. The interface is designed to communicate with the user by a mouse...
