- Abstract: We consider the problem of binary power control, or link scheduling, in
wireless interference networks, where the power control policy is trained using
graph representation learning. We leverage the interference graph of the
wireless network as an underlying topology for a graph neural network (GNN)
backbone, which converts the channel matrix to a set of node embeddings for all
transmitter-receiver pairs. We show how the node embeddings can be trained in
several ways, including via supervised, unsupervised, and self-supervised
learning, and we compare the impact of different supervision levels on the
performance of these methods in terms of the system-level throughput,
convergence behavior, sample efficiency, and generalization capability.

GDNs can learn a distribution of graphs in a supervised fashion, perform link prediction or edge-weight regression tasks by adapting the loss function, and they are inherently inductive.

This paper introduces a novel self-supervised strategy for graph representation learning by exploiting natural supervision provided by the data itself.
We randomly select pairs of nodes in a graph and train a well-designed neural net to predict the contextual position of one node relative to the other.
Our underlying hypothesis is that the representations learned from such within-graph context would capture the global topology of the graph and finely characterize the similarity and differentiation between nodes.
