I am happy to bring to your attention a new Massive Open Online Course (MOOC)

I am happy to bring to your attention a new Massive Open Online Course (MOOC) that Yaniv Romano (my PhD student) and I have constructed on Sparse Representations. Here is the link under the edX webpage. This course will open formally on October 25th this year. It is built of two 5 weeks parts, the first presents the basic theoretical ideas of sparse representations, and the other connects this model to applications in image processing. In this course we are essentially following the content of my book. We will be delighted to see you joining our course, which could provide you with a pleasant introduction to our field.

My paper with Michal Aharon on image denoising stands at the top of the list in the Signal Processing category

Google-Scholar released a list of what they refer to as the classic papers published during 2006. My paper with Michal Aharon on image denoising stands at the top of the list in theВ Signal Processing category. Also, my paper with David Donoho and Volodya Temlyakov on sparse representations is included in the classics of theВ Information Theory category.

I have been selected (again) as a Thomson-Reuters Highly Cited Researcher

I have been selected (again) as a Thomson-Reuters Highly Cited Researcher. This list contains about 3000 scientists in various disciplines. Interestingly, only 9 of this list are from Israel, and I am the only Israeli representing the subfield "Engineering". More on this list can be foundВ here.

Deep-LearningВ offering a highly effective paradigm for supervised classification and regression

Deep-LearningВ is an emerging sub-field of machine-learning, offering a highly effective paradigm for supervised classification and regression. While empirical evidence puts this tool in the very forefront of today's artificial intelligence, both in the academia and the industry, theoretical understanding of this field has been lagging behind. I am proud to announce that ourВ recent workВ (joint with Vardan Papyan and Yaniv Romano) closes much of this gap. We propose an extension of the classic theory of sparse representations, modeling signals as hierarchical sparse compositions. For these signals we are able to show that fully-connected or convolutional neural networks (NN) are in fact pursuit algorithms, aiming to decompose the signals into their building atoms. With this view, we are able to analyze the performance of NN and consider various architectural improvements.

Freddy Bruckstein (CS-Technion), David Donoho (Statistics-Stanford) and I have been selected the winners of the 2014 SIAG/Imaging Science Prize

Freddy Bruckstein (CS-Technion), David Donoho (Statistics-Stanford) and I have been selected the winners of the 2014 SIAG/Imaging Science Prize. The SIAM Activity Group on Imaging Science (SIAG/IS) will award the prize at the SIAM Conference on Imaging Science (В IS14, May 12-14, 2014, Hong Kong). The prize is awarded to the authors of the best paper on mathematical and computational aspects of imaging. Specifically, the committee referred toВ our paper, "From Sparse Solutions of Systems of Equations to Sparse Modeling of Signals and Images," SIAM Review 2009, recognizing us for our "fundamental contribution to the theory and practice of sparse representations and compressed sensing, and their popularization within the imaging science community.".
