    The structure of the systems underlying a pervasive computing environment is dynamic and continuously changing. Consequently, their architectures must have the ability to react to events and perform architectural changes autonomously. In this paper, our principle is to use our platform based agents to achieve these functionalities, to monitor the global architecture and to evaluate and manage chan... View full abstract»

    We describe a new computational cognitive model that is being developed for solving complex problems in bioinformatics. This cognitive model was developed based on observing biologists solving problems in their current environments. Bioinformatics provides several challenges to current problem-solving environments: 1) massive heterogeneous data to mine and fuse; 2) quantity of information is growi... View full abstract»

    Attribute reduction is an important issue of rough set theory and has already been separately studied in algebra view and information view. However, conceptions of attribute reduction based on the two views are not necessarily equivalent, they are the same only in consistent decision systems. In this paper, we theoretically study the quantitative relation between some basic notions of rough set th... View full abstract»

    Summary form only given. Language is primarily a physical, more particularly a biological phenomenon. To say that it is primarily so is to say that that is how, in the first instance, it presents itself to observation. It is curious then that theoreticians of language treat it as though it were primarily semantic or syntactic or a fusion of the two, and as though our implicit understanding of sema...

    DISPAR, proposed by Miikkulainen and Dyer (1991), consists of layered neural networks named FGREP modules and executes the task of parsing a story and generating a paraphrase. Patterns in input and output layers of FGREP modules are sequences of word representations, and FGREP modules communicate with each other using word representations which are updated through training. This paper makes it cle... View full abstract»

    A software release is a collection of new and/or changed features that form a new product. Release planning is a very complex problem including different stakeholder perspectives, competing objectives and different types of constraints. Most of the information is usually uncertain. Under such circumstances, the use of crisp values is only an approximation of reality. We propose an approach improvi... View full abstract»

    This paper presents a supervised ART neural network named impulse force based ART (IFART) neural network. It enhances the prediction accuracy of the supervised ART neural network using impulse forces on attributes optimized by genetic algorithm, which identify the different effect of input attributes on category results. However, the IFART neural network is still a black box and difficult to under... View full abstract»

    We present a formal language to specify cognitive systems. In addition to the usual characteristics of these formalisms, our language features the possibility of including stochastic time. This kind of time is useful to represent systems where the delays are not controlled by fix amounts of time, but they are given by a probability distribution function. View full abstract»

    This paper provides a review of Shannon and other entropy measures in evaluating the quality of materials used in perception, cognition and learning processes. Energy-based metrics are not suitable for cognition, as energy itself does not carry information. Instead, morphological (structural and contextual) as well as entropy-based metrics should be considered in cognitive informatics. The data an... View full abstract»

    Neural networks can be trained to approximate arbitrary nonlinear mappings. Because of this capability, they have been successfully used in applications such as system modeling, time-series prediction, automatic control and pattern recognition. In these applications, a mapping is needed to represent the input-output relationship of a real-world process. Neural networks can be trained to form this ... View full abstract»

    We introduce a programming environment to help implementing cognitive models. The language we use is specially appropriate because its high-level constructions allow the easy development of general schemes that can be easily used (and even modified) without requiring knowledge about the underlying language. In fact, it is even possible to automate the translation from a specification using a proce... View full abstract»

    Program debugging is a critical and complex activity in software engineering. Accurate and fast debugging leads to high quality software and a short time-to-market. Debugging involves a very demanding cognitive process. In a case study, we found all six levels of Bloom's taxonomy of cognitive learning, from "knowledge" through "comprehension", "application", "analysis", "synthesis", and "evaluatio...

    One of the fundamental human cognitive processes is problem solving. Most of the decisions we make relate to some kind of problems we try to solve no matter how trivial and critical the problem may be. The problem solving process entails performing in a new situation with information acquired and knowledge learned from past situations. As a higher level cognitive process, problem solving involves ... View full abstract»
