Soft Computing, Artificial Intelligence, Fuzzy Logic & Genetic Algorithm in Bioinformatics
Abstract Soft computing is creating several possibilities in bioinformatics, especially by generating low-cost, low precision (approximate), good solutions. Bioinformatics is an interdisciplinary research area that is the interface between the biological and computational sciences. Bioinformatics deals with algorithms, databases and information systems, web technologies, artificial intelligence and soft computing, information and computation theory, structural biology, software engineering, data mining, image processing, modeling and simulation, discrete mathematics, control and system theory, circuit theory, and statistics. Despite of a high number of techniques specifically dedicated to bioinformatics problems as well as many successful applications, we are in the beginning of a process to massively integrate the aspects and experiences in the different core subjects such as biology, medicine, computer science, engineering, and mathematics. Recently the use of soft computing tools for solving bioinformatics problems have been gaining the attention of researchers because of their ability to handle imprecision, uncertainty in large and complex search spaces. The paper will focus on soft computing paradigm in bioinformatics with particular emphasis on integrative research
A Geometric Interpretation of the Neutrosophic Set - A Generalization of the Intuitionistic Fuzzy Set
In this paper we generalize the intuitionistic fuzzy set (IFS),
paraconsistent set, and intuitionistic set to the neutrosophic set (NS).
Several examples are presented. Also, a geometric interpretation of the
Neutrosophic Set is given using a Neutrosophic Cube. Many distinctions between
NS and IFS are underlined.Comment: 9 pages. Presented at the 2003 BISC FLINT-CIBI International Workshop
on Soft Computing for Internet and Bioinformatics, University of Berkeley,
California, December 15-19, 2003, under the title "Generalization of the
Intuitionistic Fuzzy Set to the Neutrosophic Set
Bioconductor: open software development for computational biology and bioinformatics.
The Bioconductor project is an initiative for the collaborative creation of extensible software for computational biology and bioinformatics. The goals of the project include: fostering collaborative development and widespread use of innovative software, reducing barriers to entry into interdisciplinary scientific research, and promoting the achievement of remote reproducibility of research results. We describe details of our aims and methods, identify current challenges, compare Bioconductor to other open bioinformatics projects, and provide working examples
SOAP3-dp: Fast, Accurate and Sensitive GPU-based Short Read Aligner
To tackle the exponentially increasing throughput of Next-Generation
Sequencing (NGS), most of the existing short-read aligners can be configured to
favor speed in trade of accuracy and sensitivity. SOAP3-dp, through leveraging
the computational power of both CPU and GPU with optimized algorithms, delivers
high speed and sensitivity simultaneously. Compared with widely adopted
aligners including BWA, Bowtie2, SeqAlto, GEM and GPU-based aligners including
BarraCUDA and CUSHAW, SOAP3-dp is two to tens of times faster, while
maintaining the highest sensitivity and lowest false discovery rate (FDR) on
Illumina reads with different lengths. Transcending its predecessor SOAP3,
which does not allow gapped alignment, SOAP3-dp by default tolerates alignment
similarity as low as 60 percent. Real data evaluation using human genome
demonstrates SOAP3-dp's power to enable more authentic variants and longer
Indels to be discovered. Fosmid sequencing shows a 9.1 percent FDR on newly
discovered deletions. SOAP3-dp natively supports BAM file format and provides a
scoring scheme same as BWA, which enables it to be integrated into existing
analysis pipelines. SOAP3-dp has been deployed on Amazon-EC2, NIH-Biowulf and
Tianhe-1A.Comment: 21 pages, 6 figures, submitted to PLoS ONE, additional files
