    Summary form only given. Artificial intelligence applications, particularly those involving natural language understanding, are actually less ambitious than they, were decades ago. Statistical and machine learning techniques have had great success on tasks that can be treated without understanding, but there are many important areas that require semantic systems. The key to building more powerful ... View full abstract»

    Intelligence is a driving force or an ability to acquire and use knowledge and skills, or to inference in problem solving. This keynote lecture describes the taxonomy and nature of intelligence. It analyzes roles of information in the evolution of human intelligence, and the needs for logical abstraction in modeling the brain and natural intelligence. A formal model of intelligence is developed kn... View full abstract»

    Numerous attempts are being made to develop machines that could act not only autonomously, but also in an increasingly intelligent and cognitive manner. Such cognitive machines ought to be aware of their environments which include not only other machines, but also human beings. Such machines ought to understand the meaning of information in more human-like ways by grounding knowledge in the physic... View full abstract»

    The choice of an appropriate representation is generally assumed to play a decisive part in problem solving, both in human and computer performance. Some AI problem solvers have so far succeeded in performing automatic representation change, but none of them is actually able to do so once the resolution process is started. This inability proves to be a drawback so as to achieving a suitable repres... View full abstract»

    The quest to define human intelligence has led researchers down a large range of paths. One such path has been to search for a single psychometric measure that can be used to account for a large portion of the variance in human mental ability. Inspection time (IT) has emerged at the forefront of these efforts and is often referred to as the amount of time required to make a single observation of s... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2409 KB) | HTML iconHTML

    This paper presents a scheme for image decomposition and reconstruction, using complex Gabor wavelets. Gabor functions have been used extensively in areas related to the human visual system due to their localization in space and bandlimited properties. However, since the standard two-sided Gabor functions are not orthogonal and lead to nearly singular Gabor matrices, they have been used in the dec... View full abstract»

    In the paper a new way of pattern interpretation directed for automatic semantic categorization and image content understanding will be described. Such an understanding will be based on the linguistic theories of pattern classification and is aimed at facilitation of merit content analysis of for some classes of medical and economical patterns. The approach presented in this paper will show the gr... View full abstract»

    The understanding of data is highly relevant to how one senses and perceives them. The existing approaches for classification have been developed mainly based on exploring the intrinsic structure of dataset itself less or no emphasis paid on simulating human visual cognition. A new hyper surface classification method (HSC) has been studied since 2002. HSC is a universal classification method, in w... View full abstract»

    The theory that electoral college is more stable than direct popular vote is applied in face recognition. By simply adopting most traditional PCA approach, the experiments in this paper show a remarkably higher recognition rate than any known algorithm is reached with electoral college strategy on known FERET datasets. It indicates that a significant breakthrough can be expected by embedding elect... View full abstract»

    In this paper, we describe a real-time gradient-based multiple faces tracking (GMFT) algorithm in complex background. In GMFT method first faces are detected by combination of morphological facial feature extraction and gradient-based edge detection methods. After a face is reliably detected, it is tracked over time with a novel real-time algorithm. The algorithm has been implemented and tested un... View full abstract»

    As software systems become larger and more complex, in order to understand, manage and evolve these systems, we need better ways of characterizing and controlling their macroscopic properties. We suggest complex network theory may be useful for these purposes. In recent years, researchers have shown that many complex systems from different disciplines can be investigated as complex networks and mo... View full abstract»

    Shao and Wang have proposed a cognitive complexity measure as a metric that can be used for estimating the comprehension effort for understanding software written in imperative programming languages. The key idea of their approach is to assign a cognitive weight to basic software control structures. The more difficult a control structure is to understand, the greater is its cognitive weight. In th... View full abstract»

    In cognitive informatics, the functional complexity of software depends on three factors: internal architecture, input, and output. In the earlier proposed metrics based on cognitive informatics, these above factors are not fully considered. This paper proposes an improved cognitive complexity measure. Accordingly, new formula is developed to calculate the cognitive complexity. An attempt has also... View full abstract»

    A modified inspection-style approach is used in two studies, the second a replication variant of the first, to determine the mental models of subjects with regard to their beliefs about methodological constraints in tools. In addition to determining the degree of variability of perception and the reasons for the variability, three belief biases were discovered. The inspection-style approach suppor...

    Complexity in general is defined as "the degree to which a system or component has a design or implementation that is difficult to understand and verify ". Complexity metrics are used to predict critical information about reliability and maintainability of software systems. Object oriented software development requires a different approach to software metrics. In this paper, an attempt has been ma... View full abstract»
