Given the variety of encoding techniques, deciding between which methods to move forward with made the structural information captured an important consideration. Local structure in a graph refers to characteristics which are confined to a given node’s surrounding neighborhood. Positional encodings which ...
(1) learns a context-aware vector encoding of the geographic coordinates and (2) predicts spatial autocorrelation in the data in parallel with the main task. On spatial interpolation and regression tasks, we show the effectiveness of our approach, improving performance over different state-...
arXiv: Graph Neural Networks with Learnable Structural and Positional Representations 1. What has this paper done? The authors introduce a new type of learnable positional encoding (PE) of nodes for graph embedding like transformer in natural language processing. 2. Why positional encoding in graph ...
Positional encodingEfficient training and inferenceIn recent years, Graph Neural Networks (GNNs) have achieved substantial success in addressing graph-related tasks. Knowledge Distillation (KD) has increasingly been adopted in graph learning as a classical technique for model compression and acceleration, ...
