A novel framework called NetInfoF is proposed for measuring and exploiting usable information in node-attributed graphs. The framework consists of two modules: NetInfoF_Probe, which assesses the graph structure and node features without model training, and NetInfoF_Act, which uses this information to solve link prediction and node classification tasks. The authors claim that their approach has several advantages, including generality, principled design with theoretical guarantees, effectiveness, and scalability.

Imagine you have a network of people where each person has some characteristics (node features). You want to predict who is friends with whom or classify people into certain groups based on these characteristics. Can you tell if a graph neural network (GNN) will do well in this task? Our framework, NetInfoF, helps by measuring how much information is in the graph structure and node features without training any models. We then use this information to solve the task. This approach has several benefits, including being able to handle both link prediction and node classification, having a principled design with theoretical guarantees, being effective, and scaling well.
