Applications Of Fuzzy Logic In Bioinformatics


Book Description

Many biological systems and objects are intrinsically fuzzy as their properties and behaviors contain randomness or uncertainty. In addition, it has been shown that exact or optimal methods have significant limitation in many bioinformatics problems. Fuzzy set theory and fuzzy logic are ideal to describe some biological systems/objects and provide good tools for some bioinformatics problems. This book comprehensively addresses several important bioinformatics topics using fuzzy concepts and approaches, including measurement of ontological similarity, protein structure prediction/analysis, and microarray data analysis. It also reviews other bioinformatics applications using fuzzy techniques./a




Fuzzy Systems in Bioinformatics and Computational Biology


Book Description

Biological systems are inherently stochastic and uncertain. Thus, research in bioinformatics, biomedical engineering and computational biology has to deal with a large amount of uncertainties. Fuzzy logic has shown to be a powerful tool in capturing different uncertainties in engineering systems. In recent years, fuzzy logic based modeling and analysis approaches are also becoming popular in analyzing biological data and modeling biological systems. Numerous research and application results have been reported that demonstrated the effectiveness of fuzzy logic in solving a wide range of biological problems found in bioinformatics, biomedical engineering, and computational biology. Contributed by leading experts world-wide, this edited book contains 16 chapters presenting representative research results on the application of fuzzy systems to genome sequence assembly, gene expression analysis, promoter analysis, cis-regulation logic analysis and synthesis, reconstruction of genetic and cellular networks, as well as biomedical problems, such as medical image processing, electrocardiogram data classification and anesthesia monitoring and control. This volume is a valuable reference for researchers, practitioners, as well as graduate students working in the field of bioinformatics, biomedical engineering and computational biology.




Fuzzy Logic in Medicine


Book Description

To say that Fuzzy Logic in Medicine, or FLM for short, is an important addi tion to the literature of fuzzy logic and its applications, is an understatement. Edited by two prominent informaticians, Professors S. Barro and R. Marin, it is one of the first books in its field. Between its covers, FLM presents authoritative expositions of a wide spectrum of medical and biological ap plications of fuzzy logic, ranging from image classification and diagnostics to anaesthesia control and risk assessment of heart diseases. As the editors note in the preface, recognition of the relevance of fuzzy set theory and fuzzy logic to biological and medical systems has a long history. In this context, particularly worthy of note is the pioneering work of Profes sor Klaus Peter Adlassnig of the University of Vienna School of Medicine. However, it is only within the past decade that we began to see an accelerat ing growth in the visibility and importance of publications falling under the rubric of fuzzy logic in medicine and biology -a leading example of which is the Journal of the Biomedical Fuzzy Systems Association in Japan. Why did it take so long for this to happen? First, a bit of history.

An Introduction to Fuzzy Sets


Book Description

The concept of fuzzy sets is one of the most fundamental and influential tools in computational intelligence. Fuzzy sets can provide solutions to a broad range of problems of control, pattern classification, reasoning, planning, and computer vision. This book bridges the gap that has developed between theory and practice. The authors explain what fuzzy sets are, why they work, when they should be used (and when they shouldn't), and how to design systems using them. The authors take an unusual top-down approach to the design of detailed algorithms. They begin with illustrative examples, explain the fundamental theory and design methodologies, and then present more advanced case studies dealing with practical tasks. While they use mathematics to introduce concepts, they ground them in examples of real-world problems that can be solved through fuzzy set technology. The only mathematics prerequisites are a basic knowledge of introductory calculus and linear algebra.




Applications of Fuzzy Logic in Bioinformatics


Book Description

A man disappears. The woman who loves him is left scarred and haunted. In her fierce, one-of-a-kind debut, Rebecca Lindenberg tells the story—in verse—of her passionate relationship with Craig Arnold, a much-respected poet who disappeared in 2009 while hiking a volcano in Japan. Lindenberg’s billowing, I-contain-multitudes style lays bare the poet’s sadnesses, joys, and longings in poems that are lyric and narrative, at once plainspoken and musically elaborate. Regarding her role in Arnold’s story, Lindenberg writes with clear-eyed humility and endearing dignity: “The girl with the ink-stained teeth / knows she’s famous / in a tiny, tragic way. / She’s not / daft, after all.” And then later, playfully, of her travels in Italy with the poet, her lover: “The carabinieri / wanted to know if there were bears / in our part of America. Yes, we said, / many bears. Man-eating bears? Yes, of course, / many man-eating bears.” Every poem in this collection bursts with humor, pathos, verve—and an utterly unique, soulful voice. This widely anticipated debut, already selected as a finalist for several prominent book awards, marks the first collection in the newly minted McSweeney’s Poetry Series. MPS is an imprint which seeks to publish a broad range of excellent new poetry collections in exquisitely designed hardcovers—poetry that’s useful and meaningful to anyone in any walk of life.
