    For automatic obstacle avoidance guidance during rotorcraft low altitude flight a reliable model of the nearby environment is needed. Such a model may be constructed by applying surface fitting techniques to the dense range map obtained by active sensing using radars. However, for covertness passive sensing techniques using electro-optic sensors is desirable. As opposed to the dense range map obta... View full abstract»

    A Bayesian network is a probabilistic representation for uncertain relationships, which has proven to be useful for modeling real-world problems. When there are many potential causes of a given effect, however, both probability assessment and inference using a Bayesian network can be difficult. In this paper, we describe causal independence, a collection of conditional independence assertions and ... View full abstract»

    White (1986) and Snow (1991) have presented approximate characterizations for the posterior probabilities when the priors and conditionals are specified through linear constraint systems. This paper extends their results by developing alternative linear inequality approximations for posterior probabilities, with a particular focus on partial information expressed in terms of (i) bounds on the comp...

    Recently, there has been a great increase in interest in using three dimensional stereoscopic displays to provide viewers with realistic 3D views of objects of interest. Some applications where stereoscopic displays are becoming popular include medical visualization, visualization of meteorological data, and various virtual reality applications. To quantify the effectiveness of stereoscopic system... View full abstract»

    We present a decision support system which is based on the transferable belief model (TBM), a model to represent someone's degree of belief based on belief functions. The system performs reasoning and decision making by integrating a system for belief propagation and a system for Bayesian decision analysis. The two subsystems are developed within the framework of the valuation-based systems. They ... View full abstract»

    Acquiring new knowledge without interfering with old knowledge is a key issue in designing an incremental-learning system. The success of such a system hinges on an embedded incrementable information structure with improved performance over time. This paper describes an incremental-learning network for pattern recognition that uses a rule-based connectionist technique to represent general domain a... View full abstract»

    Uncertainty is defined in a new manner, as a function of discrete probability distributions satisfying a simple and intuitively appealing weak monotonicity condition. It is shown that every uncertainty is Schur-concave and conversely, every Schur-concave function of distributions is an uncertainty. General properties of uncertainties are systematically studied. Many characteristics of distribution... View full abstract»

    A variety of real-world problems can be formulated as continuous optimization problems with variable constraint. It is well-known, however, that it is difficult to develop a unified method for obtaining their feasible solutions. We have recognized that the recent work of solving the traveling salesman problem (TSP) by the Hopfield model explores an innovative approach to them as well as combinator... View full abstract»

  • A composite object model of an urban water network based on multidisciplinary knowledge bases. I. Composite object modeling

    In order to model an urban water network, modelers have to cope with the interdisciplinary nature of the water network. To deal with the interdisciplinary nature, we have developed composite object modeling, a framework for constructing models on the basis of multiple domain knowledge bases. This modeling framework utilizes not only multiple domain knowledge, but also interface knowledge that brid... View full abstract»

    This paper gives a formal model for blackboard systems that provides a consistent method for describing a blackboard system. The formal model describes the basic components of a blackboard system and how the components interact. A set of blackboard system design tools has been developed and validated for implementing systems that are expressed using the formal model. The tools are used to test and... View full abstract»

    This paper describes research on an algorithm for improving the efficiency of the algorithm of Huhns and Bridgeland (1991) for justification-based, distributed reason maintenance (DRM). Improvements are made by ordering the relabel attempts by relative group adaptability, a measure of the relative difficulty of achieving a consistent relabeling of shared beliefs among a group of agents.

    We present a kinematic model of a paraplegic subject walking with crutches where the subject with the crutches is modeled as a parallel kinematic structure. The model is employed to investigate if certain quadrupedal gait patterns can be implemented with functional electrical stimulation. The study is motivated by the fact that the existing crutch-assisted gait realized by the electrical stimulati... View full abstract»

    We describe a decision-theoretic methodology for case-based reasoning in diagnosis and troubleshooting applications. The system utilizes a special-structure Bayesian network to represent diagnostic cases, with nodes representing issues, causes, and symptoms. Dirichlet distributions are assessed at knowledge acquisition time to indicate the strength of relationships between variables. During a diag... View full abstract»

    The focus of this work is to provide a procedure for aggregating prioritized belief structures. Motivated by the ideas of nonmonotonic logics an alternative to the normalization step used in Dempster's rule when faced with conflicting belief structures is suggested. We show how this procedure allows us to make inferences in inheritance networks where the knowledge is in the form of a belief struct... View full abstract»

    This paper considers the problem of modeling an unknown system by a rule-based model constructed from measured data. In particular, we address two fundamental issues associated with the rule-based modeling: rule-base construction and rule-base manipulation. A two-step approach consisting of a principal and a refining algorithm has been suggested to extract rules from the available data set. Starti... View full abstract»

    We consider the problem of recognizing the driving environment of a vehicle by using information obtained from some sensors of the vehicle. Previously, we presented a recognition algorithm based on an usual method of pattern matching by use of fuzzy reasoning. Furthermore, this algorithm was extended to meet the demands of nonstandard drivers and changes of vehicle properties. In this algorithm we... View full abstract»

    This paper considers the problem of determining the optimal distributed decision strategy for a team of decision-makers (DMs) arranged in an arbitrary acyclic organizational structure and controlling a complex structured process. Each DM has access to uncertain and partial information about the task environment and can control only a portion of it. We present an influence diagram model of the join... View full abstract»
