CHAPTER 1 INTRODUCTION PROTEIN SEQUENCE Proteins (Y.Vincent, et al.) are present in every cell of the organisms. They are involved virtually almost in all cellular activities. They are responsible for the various metabolic activities, nutrition transportation, regulations and etc. They exist as single chain molecule, as a three dimensional structures or even in the bundle or complex forms. The protein plays a vital role in cellular processes. The protein consists of twenty amino acids. They possess
f9. OVERVIEW OF WEB DOCUMENT CLUSTERING ALGORITHMS: In this section, we present an overview of web document clustering algorithms in some detail. Salton (1971) [1] proposed vector space model to represent text documents in vectors in a feature space. Terms in a document collection were taken as features. The feature values are computed by using various weighting schemes. Term-Frequency and Inverse Document Frequency(tf*idf) is the most commonally used term weighting scheme . [53] provides the
constraints, it would be logical, that optimization of an algorithm program should be as easy as optimization of a new product or system. An optimized optimization-algorithm should minimize the resources needed to converge on the solution it is attempting to optimize resulting in faster execution time and utilization of fewer processing resources such as memory or more capable processor. Optimization of an optimization-algorithm may at times be redundant since the optimization algorithm has already produced
computing technique with the help of clustering approach and Differential Evolution algorithm. Index Terms—Big Data, K-means algorithm, DE (Differential Evolution), Data clustering Introduction Day by day amount of data generation is increasing in drastic manner. Where in to describe the data, for zetta byte, popular term used is “Big data”. The marvelous volume and mixture of real world data surrounded in massive databases clearly overcome old-fashioned manual method of data analysis, such as worksheets
formation techniques used in wireless sensor network. In which, Particle Swarm Optimization (PSO) is simple and efficient optimization algorithm, which is used to form the energy efficient clusters with optimal selection of cluster head. The comparison is made with the well-known cluster based protocols developed for WSN, LEACH (Low Energy Adaptive Clustering Hierarchy) and LEACH-C as well as the traditional K-means clustering algorithm. A comparative analysis shown in the paper and come to the conclusion
switch to exploitation stage much too immediately, it may result in stagnation after certain first stage. So that you can improve the overall performance, several methods and even procedures have already been examined to increase the diversity of the key thereby to enhance the functionality, which produced

mining uses various techniques such as inductive logic programming, pattern recognition, image analysis, bioinformatics, spatial data analysis, decision support systems etc. for this sort of analysis. Among these methods, clustering is the most significant and extensively used method. Clustering is utmost prevalent technique that tries to isolate data into dissimilar groups such that same-group data points are alike in its characteristics with respect to a referral point, where as data points of different-groups
Abstract— Genetic Algorithm (GA) is a stochastic randomized blind search and optimization technique based on evolutionary computing that has already been proved to be robust and effective from its outcome in solving problems from variety of application domains. Clustering is a vital technique to extract meaningful and hidden information from the datasets. Clustering techniques have a broad field of application including bioinformatics, image processing and data mining. In order to the find the close
computing, and clustering methods. Basically, he proposed the optimization of a predefined CNN architecture by adjusting its weights in an unsupervised way. Initially, the CNN architecture is trained by the classical gradient-based algorithm. Extracted features are grouped by a clustering process and each group is evolved by the Differential Evolution (DE) algorithm. The weights of the CNN are then updated in an unsupervised way to represent the evolved feature vectors. The proposal of clustering
