The success of Bioinformatics in recent years has been prompted by research in mole- lar biology and medicine in initiatives like the human genome project. The volume and diversification of data has increased so much that it is very hard if not impossible to analyze it by human experts. The analysis of this growing body of data, intensified by the development of a number of high-throughput experimental techniques that are generating the so called 'omics' data, has prompted for new computational methods. New global approaches, such as Systems Biology, have been emerging replacing the...

The international conference Intelligent Information Processing and Web Mining IIS: IIPWM'05, organized in Gda?sk-Sobieszewo on 13-16th June, 2005, was a continuation of a long tradition of conferences on applications of Arti?cial Intelligence (AI) in Information Systems (IS), organized by the Institute of Computer Science of Polish Academy of Sciences in cooperation with other scienti?c and business institutions. The Institute itself is deeply engaged in research both in AI and IS and many scientists view it as a leading institution both in fundamental and - plied research in these areas in...

SVMs have emerged as very successful pattern recognition methods in recent years 16]. SVMs have yielded superior performance in various applications such as; text categorization 15], and face detection 12], content-based image retrieval 6], and learning image similarity 4]. The motivation here is detection of suspicious bags in a security situation. The usual method for bomb personnel is to blow up a suspicious bag, and any explosives contained therein. However, if the bag contains chemical, biological or radiological canisters, this may lead to disastrous results. Furthermore, the bl-...

This volume contains selected papers, presented at the international c- ference on Intelligent Information Processing and Web Mining Conference nd IIS: IIPWM 06, organized in Ustro? (Poland) on June 19-22, 2006. The event was organized by the Institute of Computer Science of Polish Academy of Sciences, a leading Polish research institution in fundamental and applied research in the area of Arti?cial Intelligence (AI) and of Inf- mation Systems (IS), in cooperation with a number of scienti?c and business institutions. It was a continuation of a series of conferences on these subjects,...

For the 8th time since 1991 we invite researchers to participate in the Do- mund Fuzzy-Days. I am very glad that our conference has established itself as an international forum for the discussion of new results in the eld of Com- tational Intelligence. Again all papers had to undergo a thorough review: each one was judged by ?ve referees to guarantee a solid quality of the programme. From the beginning of the Fuzzy-Days on, Lot? A. Zadeh felt associated withtheconference.Iwouldliketoexpressmygratitudeforhisencouragement and support and I am particularly glad that he once again delivers a...

Computational intelligence integrates fields such as neural networks, fuzzy systems, evolutionary computation and intelligent systems in general. This book contains theoretical studies as well as a chapter on applications and case studies.

Classical probability theory and mathematical statistics appear sometimes too rigid for real life problems, especially while dealing with vague data or imprecise requirements. These problems have motivated many researchers to "soften" the classical theory. Some "softening" approaches utilize concepts and techniques developed in theories such as fuzzy sets theory, rough sets, possibility theory, theory of belief functions and imprecise probabilities, etc. Since interesting mathematical models and methods have been proposed in the frameworks of various theories, this text brings together...
