WebAug 25, 2024 · The horizontal axis is the number of iterations of our model (epochs), which can be regarded as the length of model training; the vertical axis is the loss of the data set.The larger the loss, the less accuracy of data prediction. This is the principle of early stopping.. Since the model will gradually start overfitting, why not stop training when the … WebTo support heterogeneity of nodes and edges we propose to extend the GraphSAGE model by having separate neighbourhood weight matrices (W neigh ’s) for every unique ordered tuple of (N1, E, N2) where N1, N2 are node types, and E is an edge type. In addition the heterogeneous model will have separate self-feature matrices Wself for every node ...
