––The data clustering is a big problem in a wide variety of different areas,like pattern recognition & bio-informatics. Clustering is a data description method in data mining which collects most similar data. The purpose is to organize a collection of data items in to clusters, such that items within a cluster are more similar to each other than they are in(More)

We apply Adomian decomposition method (ADM) for obtaining approximate series solution of Urysohn integral equations. The ADM provides a direct recursive scheme for solving such problems approximately. The approximations of the solution are obtained in the form of series with easily calculable components. Furthermore, we also discuss the convergence and(More)
— Education Data Mining is a promising discipline which has an imperative impact on predicting students' academic performance. In this paper, student's performance is evaluated using association rule mining algorithm. Research has been done on assessing student's performance based on various attributes. In our study important rules are generated to measure(More)

Singular value decomposition (SVD) based algorithm is designed to compress the black and white images to evaluate the effect of information content of the image. Inorder to evaluate the effect second algorithm is developed to calculate the SNR, PSNR, MSE, and RMSE value of the compressed images with respect to reference image. It is interpreted from the(More)
