Gradient Derivation for Learnable Parameters in Graph Attention Networks
This work offers incremental analysis for researchers using Graph Attention Networks to understand and potentially improve model training.
The authors derived the parameter gradients for GATv2 to address inconsistent performance across datasets, providing insights into training dynamics without reporting specific numerical results.
This work provides a comprehensive derivation of the parameter gradients for GATv2 [4], a widely used implementation of Graph Attention Networks (GATs). GATs have proven to be powerful frameworks for processing graph-structured data and, hence, have been used in a range of applications. However, the achieved performance by these attempts has been found to be inconsistent across different datasets and the reasons for this remains an open research question. As the gradient flow provides valuable insights into the training dynamics of statistically learning models, this work obtains the gradients for the trainable model parameters of GATv2. The gradient derivations supplement the efforts of [2], where potential pitfalls of GATv2 are investigated.
