ACKNOWLEDGMENTS First of all, I would like to express my special appreciation to my advisor, Dr. Ming Dong, for his guide of my professional development and an inexhaustible source of ideas through my Ph.D.program at Wayne State University. During these years, he has spent tremendous time and effort with me discussing research, teaching me to write papers, and answering my questions. Without hi...

Data analysis is pervasive throughout business, engineering and science. Very often the data to be analyzed is nonnegative, and it is often preferable to take this constraint into account in the analysis process. Here we are concerned with the application of analyzing data obtained using astronomical spectrometers, which provide spectral data which is inherently nonnegative. The identification ...

We introduce a novel Bayesian hybrid matrix factorisation model (HMF) for data integration, based on combining multiple matrix factorisation methods, that can be used for inand out-of-matrix prediction of missing values. The model is very general and can be used to integrate many datasets across different entity types, including repeated experiments, similarity matrices, and very sparse dataset...

Perfusion decellularization of cadaveric hearts removes cells and generates a cell-free extracellular matrix scaffold containing acellular vascular conduits, which are theoretically sufficient to perfuse and support tissue-engineered heart constructs. This article contains additional data of our experience decellularizing and testing structural integrity and composition of a large series of hum...

domain ΩT domain ΩS "well-separated" xi yi Specifically, let’s say we have domains ΩS of N source points and ΩT of M target points, and these domains are “well-separated” (we will formalize this in section 3). Our goal is to compute the influence of all source points onto target points. Let the M × N matrix [K]ij = K(xi, yj) and assume it is approximately low-rank, so that K ≈ UV T with U of si...

UNLABELLED We describe a simple software tool, 'matrix2png', for creating color images of matrix data. Originally designed with the display of microarray data sets in mind, it is a general tool that can be used to make simple visualizations of matrices for use in figures, web pages, slide presentations and the like. It can also be used to generate images 'on the fly' in web applications. Both c...

The amount of data that is being produced has increased rapidly so has the various data mining methods with the aim of discovering hidden patterns and knowledge in the data. With this has raised the problem of confidential data being disclosed. This paper is an effort to not let those confidential data be disclosed. We apply constrained nonnegative matrix factorization (NMF) in order to achieve...

Due to increasing the usage of media, the utilization of video play central role as it supports various applications. Video is the particular media which contains complex collection of objects like audio, motion, text, color and picture. Due to the rapid growth of this information video indexing process is mandatory for fast and effective retrieval. Many current indexing techniques fails to ext...
