Unsupervised machine learning

The formulated optimization problem is a non-linear programming problem and, thus, is non-convex and challenging to solve, especially when the number of users becomes large. Sparked by the correlation features of the users’ channels in mm-wave-NOMA systems, we develop a K-means-based machine learning algorithm for user clustering.
