Abstract | Remote estimation over communication channels of limited capacity is an area of research with applications spanning many economically relevant areas, including cyber-physical systems and the Internet of Things. One popular choice of communication/scheduling policies used in remote estimation is the class of event-triggered policies. Typically, an event- triggering threshold is optimized, assuming complete knowledge of the system's underlying probabilistic model. However, this information is seldom available in real-world applications. This paper addresses the learning of an optimal threshold policy based on data samples collected at the sensor. Leveraging symmetry, quasi-convexity, and the method of Kernel density estimation, we propose a data-driven algorithm, which is guaranteed to converge to a globally optimal solution. Moreover, empirical evidence suggests that our algorithm is more sample-efficient than traditional learning approaches based on empirical risk minimization. |
