Compressed Sensing and Its Applications : Third International MATHEON Conference 2017 The chapters in this volume highlight the state of the art of compressed sensing and are based on talks given at the third international MATHEON conference on the same topic held from December 4 8 2017 at the Technical University in Berlin. In addition to methods in compressed sensing chapters provide insights into cutting edge applications of deep learning in data science highlighting the overlapping ideas and methods that connect the fields of compressed sensing and deep learning. Specific topics covered include: Quantized compressed sensing Classification Machine learning Oracle inequalities Non convex optimization Image reconstruction Statistical learning theory This volume will be a valuable resource for graduate students and researchers in the areas of mathematics computer science and engineering as well as other applied scientists exploring potential applications of compressed sensing An Introduction to Compressed Sensing Quantized Compressed Sensing: a Survey On reconstructing functions from binary measurements Classification scheme for binary data with extensions Generalization Error in Deep Learning Deep learning for trivial inverse problems Oracle inequalities for local and global empirical risk minimizers Median Truncated Gradient Descent: A Robust and Scalable Nonconvex Approach for Signal Estimation Reconstruction Methods in THz Single pixel Imaging
