Bagging the Peaks: Matrix and Tensor Factorization with Unimodal Constraints

We consider matrix and tensor factorization problems where there are unimodal constraints. Such methods find application in a variety of problems such as target localization, environmental monitoring, epidemic detection, and medical diagnosis. We presume that we have incomplete (sparse) and noisy samples of a particular field or image and that …

Communication, sensing and control in large scale wireless networks

Modern wireless technology enables the vision of future large scale systems such as the SmartGrid, a network of ubiquitous and heterogeneous devices wirelessly connected to the Internet, and wireless health monitoring and health modifying sensor networks over communities and not just individuals. All of these applications necessitate methods that simultaneously …
