  • Modelling human cognition: a singular task

    Publication Year: 1995
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (74 KB)

    Summary form only given. The cognitive literature has debated at some length the rival merits of models in which there are associationist connections and implicit rules and models in which there are explicit, syntactically structured rules. Human cognition represents a singular challenge to both models for reasons that only emerge when we undertake an analysis of the nature of human cognitive adap... View full abstract»

  • Emulating fuzzy mappings with a neural network architecture

    Publication Year: 1995, Page(s):251 - 254
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (259 KB)

    We propose a neural network model for the processing of fuzzy data. The network parameters (weights) are standard real numbers and the spreads at the output level result exclusively from uncertainty in the input data. Our network model performs 'intelligent' inference calculations on the basis of fuzzy data and minimizes uncertainty in the final output. The number of free parameters (weights) in o...

    This paper describes the design and implementation of an expert system based questionnaire system. The concept of a questionnaire is examined from a process model and an information model point of view. From the questionnaire models two expert system implementations have been designed and implemented. Finally the shortcomings and advantages are presented and discussed View full abstract»

  • Conceptual distance of numerically specified case features

    Publication Year: 1995, Page(s):210 - 213
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (376 KB)

    Case-based reasoning (CBR) systems rely on the conceptual ordering of entities called cases. If atomic case features are allowed to assume numeric as well as symbolic values, then a systematic comparison regime is needed to aggregate similarity scores. A common approach to deal with real-numbered features is normalisation. However, there are two conspicuous problems with this procedure: the simila... View full abstract»

    We present results from our research work on the parallel processing of knowledge-base systems, for which a new computational model has been developed. The focus is on the preprocessing aspect of this model, which plays a crucial role in reducing the communication overheads and establishing a suitable environment for run-time processing. Algorithms have been developed for three operations: the clu... View full abstract»

    This paper investigates the use of an artificial neural network (ANN) to estimate the six hour rainfall over the south-east coast of Tasmania. ANNs are becoming increasingly prominent in many areas of weather forecasting due to their potential to capture the complex relationships between the many factors that contribute to certain weather conditions. The estimations produced by the ANNs were compa... View full abstract»

  • Fuzzy reasoning method for smooth interpolation

    Publication Year: 1995, Page(s):120 - 123
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB)

    The paper describes a fuzzy reasoning method whose result belongs to the C1 class. The proposed fuzzy reasoning method refers to interpolation by man. We suppose that humans consider two directions while interpolating. A direction of fluctuation at a given point is one, and a direction toward neighboring data is the other. Both directions are reflected in the consequent part of the fuzz... View full abstract»

  • An expert project management assistant

    Publication Year: 1995, Page(s):198 - 201
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB)

    The paper discusses the management of large multi-layer projects and the need for computer assistance in the development of cohesive planning. Any system that purports to assist an experienced project manager, must itself contain embedded intelligence to be of any use. As projects are fragmented and subsequently abstracted back into the parent-project, limited recursive procedures must indicate th... View full abstract»

  • An approach to design fuzzy IF-THEN rules for fuzzy-controlled static VAr compensator

    Publication Year: 1995, Page(s):116 - 119
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (280 KB)

    The paper describes an approach to design fuzzy IF-THEN rules for the fuzzy-controlled static VAr compensator (FCSVC) in a three-phase electric power system. In general, designing fuzzy IF-THEN rules for fuzzy-controlled non-linear MIMO systems is very difficult because the system is too complex to obtain the knowledge of experts sufficiently. Therefore, automatic design of the rules from input-ou... View full abstract»

    Research into associative learning has been under taboo within AI for more than three decades. The author argues that the prospects of associative learning are too good for this to be allowed to continue. He discusses the development of STeLLA learning robot, PURR-PUSS system and the application of the CMAC neural network View full abstract»

    The development of knowledge based systems and decision support systems that provide advice on policy, law and legislation is still in its infancy. Such systems require a degree of expertise to be embedded within them. This paper describes the process of development of a compliance system that interprets a subset of the rules and regulations of the European Community's Common Agricultural Policy (...

    In industrial sawmills, bandsaws must work at a high production rate. Two major factors which limit cutting performance are cracking and instability of the saw blades. This paper describes the results from the development of a diagnostic system which monitors blade vibration and blade tension sensor data to estimate crack length using neurocomputing techniques, to help predict blade failure.

    Some generalizations of Dunn's (1973) index for validation of crisp clusters are discussed. Numerical examples suggest that this index, which uses the standard measures for inter-set distance and set diameter can be improved by using different functions for either or both of these operators View full abstract»

    In the coming 21st century, “global communication among different languages” will become more promising and more realistic. However, despite the great expectations of society for such an ideal speech translating system, there remains a great number of difficult problems related to acoustic and linguistic phenomena that need to be overcome. This is because spoken language is characteriz... View full abstract»
