Abstract

The upcoming 5G embraces network densification as a key enabling technology to meet the ever-increasing demand in capacity. With more and more radio access points, tremendous burdens will be put on the algorithmic aspect of wireless communications. In particular, computationally efficient algorithms are needed for solving various high-dimensional, typically non-convex, resource allocation problems in wireless dense networks (DenseNets). Meanwhile, we have recently witnessed the success of applying machine learning techniques to different application domains, including solving optimization problems. This talk will present a machine learning based framework for mixed-integer resource allocation problems in DenseNets. Compared with existing studies on “learning to optimize” for wireless networks, this new framework requires much fewer training samples; it is capable of transferring to a new network setting with a few additional unlabeled samples; it can outperform sub-optimal algorithms that are used to generate training samples.
