Facts mining and knowledge modelling are lower than quickly improvement. due to their large purposes and learn contents, many practitioners and teachers are drawn to paintings in those components. with a purpose to selling verbal exchange and collaboration one of the practitioners and researchers in Hong Kong, a workshop on info mining and modelling was once held in June 2002. Prof Ngaiming Mok, Director of the Institute of Mathematical learn, The collage of Hong Kong, and Prof Tze Leung Lai (Stanford University), C.V. Starr Professor of the collage of Hong Kong, initiated the workshop. This paintings comprises chosen papers awarded on the workshop. The papers fall into major different types: facts mining and information modelling. facts mining papers care for trend discovery, clustering algorithms, category and sensible purposes within the inventory marketplace. facts modelling papers deal with neural community versions, time sequence types, statistical types and sensible purposes.

The extra our society is dependent upon digital sorts of communique, the extra the protection of those verbal exchange networks is vital for its well-functioning. consequently, study on tools and methods to enhance community protection is intensely vital. subject matters during this quantity comprise the most recent advancements in: protection protocols; safe software program engineering; cellular agent protection; E-commerce protection; protection for disbursed computing.
Peace-Maintenance explores the arguable idea that has developed from diplomatic peacekeeping and armed forces peace-enforcement. Jarat Chopra, the architect of peace-maintenance, outlines the constraints of conventional peacekeeping ideas reliant at the more and more questionable consent of belligerents.
"One can't speak about arithmetic within the sixteenth and seventeenth centuries with no seeing a Jesuit at each corner," George Sarton saw in 1940. * Sarton, after all, was once no longer the 1st to acknowledge the disproportionate illustration of individuals of the Society of Jesus within the clinical company of the early smooth interval.

Therefore, the rank ( T I , . . ,T ~ should ) be a good approximation to the true ordering in the UDS solution. We illustrate this method by two examples taken from Robinson 7: the 8 x 8 dissimilarity matrix for the Mani collection of archaeological deposits, and a 17 x 17 matrix for the Kabah collection. These examples + 43 were also used as test cases by Hubert and Arabie Leung and Tse 5 . 4, Pliner and Lau, Table 1. Dissimilarity matrix from Mani collection. 58 Table 1 gives the 8 x 8 dissimilarity matrix and their row total Si.

The fuzzy versions of k-means type algorithms The k-means, k-modes and k-prototypes algorithms are called hard clustering algorithms because they assign each data object into only one cluster. However, objects in different clusters often overlap at boundaries. Instead of assigning each boundary object into only one cluster, the boundary objects can be assigned to more than one cluster with different confidence levels. The fuzzy versions of these algorithms are designed for this purpose. Let X be a set of n objects described by m attributes.
