This study presents PRISM, a probabilistic simplex component analysis approach to identifying the vertices of data-circumscribing from data. The problem has rich variety applications, most notable being hyperspectral unmixing in remote sensing and non-negative matrix factorization machine learning. PRISM uses simple model, namely, uniform data distribution additive Gaussian noise, it carries ou...

A Software Repository is a collection of library files and function codes. Programmers and Engineers design develop and build software libraries in a continuous process. Selecting suitable function code from one among many in the repository is quite challenging and cumbersome as we need to analyze semantic issues in function codes or components. Clustering and Mining Software Components for eff...
