It is emphasized that using the strong capabilities of human visual reasoning in the analysis of complex systems may be an effective way of dealing with their complexity. An effective visualization process based on geometric 2-D/3-D representations of multidimensional spaces as well as clustering procedures constitutes the key to the process. Defining an appropriate reference model is also important and possible if a deep knowledge of the system is available. A simple demonstration model developed to evaluate some ideas of the proposed system is described.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

This neural network has ML neurons, which adaptively estimate the local metric in the classification space. This permits the design of flexible classifier shapes using a no-hidden-layer architecture and provides orders-of-magnitude improvement in learning efficiency. The learning efficiency of this network approaches the Cramer-Rao bounds with a relatively small number of samples. The learning process of MLANS can be unsupervised learning with partial or imperfect supervision. The ML approach allows for optimal fusion of all available information, such as a priori and real-time information, including supervisory (training) information.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

The first difficulty is to propagate the domain of definition of the variables along the knowledge base using the AND/OR transitive relations between rules. The second problem is to upgrade the algorithm that has been defined for the consistency maintenance of the knowledge base for propositional logic to the level of logic with global variables. Answers are given to both problems: (1) the principles for chaining rules with global variables are given; (2) tools for computing the propagation of the domain of variables along the knowledge base are defined; (3) consistency definitions are given and tools for maintaining the consistency of the knowledge base as it incrementally increases are proposed.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

This formulation dispenses with the assumption that the operator has an accurate internal model of the system dynamics and other parameters affecting his control behavior. It has applications to learning and transfer of training situations where the operator refines his behavior over a period of time. Validation of the model is via analysis of a flight control experiment using a discrete transfer of the training protocol.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

In order to investigate their hierarchical structure the author considers such systems as topological spaces. These systems are partitioned into numerous subsystems, cells or elements in the process of their analysis and design. Such decomposition is equivalent to representation of the corresponding topological space as a disjoint union of cells. A topological cell complex of some space X is built as a quotient space of X, which is constructed by representation of each cell as one point. Thus cell complexes and CW-complexes of topological spaces are considered as topological spaces with quotient topology. Such topological complexes contain fewer points than corresponding spaces, and preserve their structure. This feature makes them useful for structural systems analysis and design.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

In the first study, a network was trained to predict the next position of an agent which was moving in a complex pattern around the corners of a square. The network quickly learned to predict the position without error. In particular, the network may be said to have developed an agent or user model of the moving agent. In two additional studies, a joint contingency was applied to two agents and limited cooperation was developed between them. Overall, the results provide support for the application of neural networks in distributed AI (artificial intelligence).<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

Identifying consistent patterns in their behavior can reveal these implicit strategies. Logs from a simulated process plant were used to identify production rules characterizing operators' behavior. Similarity among strategies was determined by finding the intersections and unions among the preconditions of these rules. Clusters of subjects using similar strategies were identified and compared on performance measures. This characterization of strategies provided a good account of differences in performance which were readily interpretable in terms of the task. The approach appears promising as a technique for diagnosing performance in simulator training.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.

Hence, in order to size the DASD subsystems within a distributed environment appropriately, a flexible and robust planning tool is needed. A planning tool in the form of a robust simulation-based model is proposed for the performance evaluation of noncached and cached DASD subsystems. It is validated with performance data obtained from a real-world environment. This planning tool is part of an ongoing research project in the development of a four-level distributed information system simulator.<<ETX>>","PeriodicalId":72691,"journal":{"name":"Conference proceedings.
