02.09.2021 · See more in Graph Attention Networks . Graph-valued data in the wild Graphs are a useful tool to describe data you might already be familiar with. Let’s move on to data which is more heterogeneously structured. In these examples, the number of neighbors to each node is variable (as opposed to the fixed neighborhood size of images and text).

Overview

03.12.2021 · Previous graph attention networks applied to materials science used simple fully connected neural networks (FCNNs) to calculate a number of coefficients (2) from the concatanation ‖ of the two vertex representations and the edge representation. Here, and in the following equations, the index n counts the number of FCNNs.
