Novel Approach Proposed
Professor Ali Akansu of the Helen and John C. Hartmann Department of Electrical and Computer Engineering and his PhD student, Mr. Onur Yilmaz have published a new paper entitled "Quantization of Eigen Subspace for Sparse Representation" published in the July issue of IEEE Transactions on Signal Processing. The paper proposes a novel approach based on the rate-distortion theory to design sparse subspaces with the applications spanning the range from constructing investment portfolios to recommending systems for e-commerce. They also presented another paper with the title, A Method to Sparse Eigen Subspace and Eigen Portfolios" at the International Conference on Information Fusion in 2015.
