We discuss a simple sparse linear problem that is hard to learn with any algorithm that uses a linear combination of the training instances as its weight vector. The hardness holds...
Recent work establishes a direct link between the complexity of a linear logic proof in terms of the exchange rule and the topological complexity of its corresponding proof net, ex...
Totally asynchronous code-division multiple-access (CDMA) systems are addressed. In part I, the fundamental limits of asynchronous CDMA systems were analyzed in terms of total cap...
Many challenging tasks in sensor networks, including sensor calibration, ranking of nodes, monitoring, event region detection, collaborative filtering, collaborative signal proces...
— During an emergency response, access to a reliable communication infrastructure is required to exchange accurate information in a timely manner. Various communication technolog...
