    The interfaces of the future are more closely adapted to the way humans naturally work and live. This attitude is supported by the development of adaptive communication between users and interactive systems. Adaptive systems, unlike traditional "one-size-fits-all" ones, can afford more personalized user interaction in a variety of contexts, including computer-based education. The paper elaborates ...

    Information of any kind always involve some kind of uncertainty, inaccuracy. The model used to represent the information during the information processing can affect the achievable preciseness and can determine the usability of different computing methods, as well. The data model must also be able to represent the uncertainty, inaccuracy of both the input data and the results. The two most popular... View full abstract»

    One of the tasks of data mining is classification, which provides a mapping from attributes (observations) to pre-specified classes. Classification models are built by using underlying data. In principle, the models built with more data yield better results (are more accurate). However, the relationship between the available data and the performance is not well understood. How much data to use, or... View full abstract»

    In the development of any technology there is always a tendency to lose sight of the basic problems that stimulated its introduction. There is very little quantitative research regarding the question whether object-oriented programming really improves productivity. Many assume that object-oriented programming is more productive than traditional structured programming. The assumption lacks concrete... View full abstract»

    The design and implementation of a control program for biped walking robots using the genetic algorithms (GA) are presented. The most difficult problem with biped walking robots is that they have too many possible gaits. Generally it is impossible to find the optimal gait for a given route. In order to control biped walking robots, we have employed GA to determine the gaits of the robots. It is kn... View full abstract»
