— In this paper we describe the geometrical interpretation of SVD based on the Pythagoras Theorem and optimization theory. SVD is a technique which factorizes matrix A into three matrices U,∑,V, such that T V U A ∑ =. The aim of this paper is to provide an easy way to understand SVD by using Pythagoras Theorem. SVD has variety of applications astro physics(More)
We propose a kernel function called Wavelet Assignment graph kernel for graph classification which has applications in drug discovery. This is an extension of wavelet alignment graph kernel. In this method we use graphs to model chemical compounds. For feature extraction we have applied wavelet analysis to graph structured chemical structure, for each atom(More)
