    The author has developed an effective method for modelling very complex systems, called n-port symbolic neural (NPSN) modeling. Both production-rule sets and back-propagation multilayer neural nets are used as building blocks. This method is effective for the development of 'trained' models of real physical systems both for simulation of the system as built (with possible faults), and for the mode... View full abstract»

    The authors consider the problem of a stochastic learning automaton interacting with an unknown random environment. The fundamental problem is that of learning, through interaction, the best action (that is, the action which is rewarded optimally) allowed by the environment. By using running estimates of reward probabilities to learn the optimal action, an extremely efficient pursuit algorithm was... View full abstract»

    The authors present a Markov-chain-based performance evaluation technique for a two-stage sliding-window cascaded logic (2/2*m/n) for track formation in a cluttered environment. The main features of this technique are that it avoids the need for extensive simulations and it is more realistic than previous methods in that it accounts for the variation of the association gate size. The gates are obt... View full abstract»

    A model of skilled human performance in a complex laboratory task is presented. The task required human crews to perform manual and supervisory control of multiple craft to discover and process objects in a simulated world. The model could perform the task as well as the most highly skilled human crews and could be parameterized to mimic the behavior of crews that differed in both crew size and ex...

    Cited by:  Patents (1)
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (595 KB)

    Various approaches to user modeling are presented and the possibility for verification is assessed. In a larger context, this leads to the issue of evaluating and validating combined human-machine systems in the presence of model-based and expert-system-based operator support. With such support, detailed measures and analyses of the overall system performance become more important. An example of a... View full abstract»

    An alternative to the traditional human-factors guideline document is described. This new concept for organizing principles for human-computer interaction (HCI) was developed in response to four deficiencies in existing guidelines: (a) incorrect conceptualization of the units of display design, (b) inadequate integration of principles into process, (c) unrealistic view of the design process, and (...

  • Validation of blackboard architecture for dynamic intent inferencing

    Publication Year: 1989, Page(s):35 - 39 vol.1
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (521 KB)

    The authors propose the concept of an operator's associate to serve as an intelligent aid to the human operator. They note that a necessary prerequisite for a useful and effective 'intelligent' automated aid is the ability to understand, or infer the intentions of, the human operator. This ability in turn relies on a sound model of operator performance goals in the control of the system. A good mo... View full abstract»

    The authors explore the key characteristics of an intelligent advisory system. A central feature is that human-machine cooperation should be based on a metaphor of human-to-human cooperation. ALLY, a computer-based operator's associate, is discussed which is based on a preliminary theory of human-to-human cooperation. ALLY assists the operator in carrying out the supervisory control functions for ... View full abstract»

    The authors offer a perspective on team decision-making that may be fruitful for understanding some of the dynamics. The perspective is centered around the concept of a team mind with three aspects that can be studied: behavior, consciousness, and subconsciousness. These aspects are described, along with methods for studying each. The operation of the team mind is illustrated by the functioning of... View full abstract»

    A componential model of creativity is presented, in which three essential components-domain-relevant skills, creativity-relevant skills, and intrinsic task motivation-enter into the creative process. Evidence is presented demonstrating that work environments can influence intrinsic motivation and, thus, creativity. An effort is then made to explore how motivation influences cognition.<<ETX&g...

    A study was conducted to determine what factors affect how humans detect correlation when forming mental models of complex systems. Using a paradigm that elicits the subject's mental model of a system by the subject's reconfiguration of the display, the authors conducted four experiments that illustrate humans' ability and factors affecting their ability to detect correlation in a dynamic display....

    A prescriptive approach to system design is outlined which breaks from standard expert systems research on two key points. First, the performance of a well-defined task analysis is taken to be a prerequisite for system design. It is the domain, then, and not the manner in which people cope with it, that guides the design phase. Second, an epistemological hierarchy, which recognizes expertise as a ... View full abstract»
