Aim of this work is to produce excellent accuracy with reduced feature set by a simple method. When the profile built using a feature selection method called MSNR (maximized signal to noise ratio) combined with modified fractional similarity method, it performs in a competitive manner. MSNR identifies the highly contributing features and increases the(More)
With overwhelming growth of information technology, better organization of documents is required for easy access of information. Hence the need for text categorization becomes critical. Many researchers have turned their attention towards text categorization. Text categorization is the automated assignment of predefined categories to the text documents(More)
Ascorbate peroxidase, a haem protein (EC 1.11.1.11), efficiently scavenges hydrogen peroxide (H(2)O(2)) in cytosol and chloroplasts of plants. In this study, a full-length coding sequence of thylakoid-bound ascorbate peroxidase cDNA (TatAPX) was cloned from a drought tolerant wheat cultivar C306. Homology modeling of the TatAPX protein was performed by(More)
In this paper, a meta-heuristic approach called Adaptive Hybrid Harmony Search algorithm (AHHS), which is a variant of recently developed Harmony search optimisation algorithm is proposed. The harmony search is basically conceptualized using the musical process of searching for a perfect state of harmony. The proposed algorithm is hybridised with a(More)
This paper explores the effect of profile based method for classification of Wikipedia XML documents. Our approach builds two profiles, exploiting the whole content, Initial Descriptions and links in the Wikipedia documents. For building profiles we use the negative category information which has shown to perform well for classifying unstructured texts. The(More)
In this paper we propose an adaptive metaheuristic algorithm based on differential evolution (DE) for solving combinatorial optimization problems. DE is a heuristic method that has yielded promising results for solving complex optimization problems. The potentialities of DE are its simple structure, easy use, convergence property, quality of solution, and(More)
