    This paper considers the problem of Neyman-Pearson distributed detection. In distributed detection structures, a number of subordinate decision makers decide upon the active hypothesis based on their own data, and then transmit these decisions to one or more primary decision makers. Then the Neyman-Pearson performance criterion is deployed, the objective is to maximize the probability of detection... View full abstract»

    A rule based fuzzy controller is presented for attitude stabilization of a small satellite in low earth orbit. Active control Is done by using 3-axis magneto-torquing. A preferred torque vector can not always be generated from the magnetic coils in certain regions of the orbit, due to an unfavourable direction of the geomagnetic field vector. The main objective of an acceptable control algorithm w... View full abstract»

    This paper demonstrates that a radial basis function (RBF) network can be used to estimate or predict future head-positions from samples of the current and past positions. The results, shown for a network trained and tested over a recorded head position time series, imply that the technique is a viable method for reducing latency in the head-slaved computer generated imagery of a flight simulator....

  • A criterion for knowledge base decoupling in fuzzy-logic control systems

    In a coupled rule base, more than one condition variable may link with more than one action variable within the same rule. This paper develops an analytical framework for decoupling such a rule base, with specific reference to fuzzy-logic control. The computational problem of fuzzy-logic is greatly simplified through the use of an uncoupled rule base. Conditions are derived, under which, decision ... View full abstract»

  • Asymmetric bidirectional associative memories

    Publication Year: 1994, Page(s):1558 - 1564

    Bidirectional associative memory (BAM) is a potentially promising model for heteroassociative memories. However, its applications are severely restricted to networks with logical symmetry of interconnections and pattern orthogonality or small pattern size. Although the restrictions on pattern orthogonality and pattern size can be relaxed to a certain extent, all previous efforts are at the cost of... View full abstract»

  • A multimodel approach to reasoning and simulation

    Models that are constructed within the bounds of a single paradigm are not sufficient for modeling all aspects of complex systems. Therefore, even though reasoning and simulation systems that utilize a single modeling paradigm are the current norm, we explore a multimodel approach in this paper. A multimodel approach is defined as one in which more than one model-each derived from a different pers... View full abstract»

  • Distributed simulation of timed Petri nets: basic problems and their resolution

    Presents a model of timed Petri nets which is more general than known models in terms of modeling convenience. The model consists of simple but fairly general modules. This would result in simpler and more modular codes for simulation of these systems, as compared with the known models of timed Petri nets. After discussing this model, the authors present an approach towards its distributed simulat... View full abstract»

  • Learning sequential patterns for probabilistic inductive prediction

    Suppose we are given a sequence of events that are generated probabilistically in the sense that the attributes of one event are dependent, to a certain extent, on those observed before it. This paper presents an inductive method that is capable of detecting the inherent patterns in such a sequence and to make predictions about the attributes of future events. Unlike previous AI-based prediction m... View full abstract»

    The perceptron convergence theorem played an important role in the early development of machine learning. Mathematically, the perceptron learning algorithm is an iterative procedure for finding a separating hyperplane for a finite set of linearly separable vectors, or equivalently, for finding a separating hyperplane for a finite set of linearly contained vectors. In this paper, the author shows t... View full abstract»

  • Diagnostic reasoning with fault propagation digraph and sequential testing

    Publication Year: 1994, Page(s):1552 - 1558
    Cited by:  Papers (10)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (660 KB)

    When faults in a device occur, the subdevices indicated to be at fault may not be the sources of failure. The ability of a diagnostic system to trace and locate the true sources of failure is therefore very important. This paper presents new algorithms for locating failure sources by using knowledge of device structure and fault propagation paths, and through the use of sequential testing of syste...

    The need for more effective ways to manage the risk and safety of technological systems has been widely recognized and accepted by government and industry. Traditionally, risk analysis has been considered as part of the process of planning a technological system and addressed the risk inherent in its day-to-day operations. However, risk must also be considered when responding to episodic events wh... View full abstract»

    Based on an evidential reasoning framework, a general multilevel evaluation process is developed in this paper for dealing with a multiple attribute decision making (MADM) problem with both quantitative and qualitative attributes. In this new process, a qualitative attribute may be evaluated by uncertain subjective judgments through multiple levels of factors and each of the judgments may be assig... View full abstract»

    An implementation is presented of an algorithm to solve large sequential decision analysis models. This implementation in the Pascal programming language does not use special features of Pascal, and is therefore straightforward to translate into other programming languages. Empirical results show that the algorithm requires only a modest personal computer to quickly solve decision trees with sever... View full abstract»

    The paper faces the reachability and the reversibility problems in a class of Petri nets larger than other classes investigated for the same problems. The considered class of Petri net represents a formal language to design and analyze logic controllers. These nets may be decomposed in simple structures, called elementary control tasks, linked together through a limited number of connections, givi... View full abstract»

    A new class of Petri nets (PNs), called parameterized Petri Nets (PPNs), is proposed and applied for planning and coordination of intelligent systems. The PPN approach uses a hierarchical organization to deal with the complexity characteristic of net representations, through parameterization of transitions and the use of generalized or parameterized places in higher level nets.
