WebIn this article, we propose a novel heterogeneous graph neural network-based method for semi-supervised short text classification, leveraging full advantage of limited labeled data and large unlabeled data through information propagation along the graph. ... Then, we propose Heterogeneous Graph Attention networks (HGAT) to embed the HIN for ... WebIn this example we use two GAT layers with 8-dimensional hidden node features for the first layer and the 7 class classification output for the second layer. attn_heads is the number of attention heads in all but the last GAT layer in the model. activations is a list of activations applied to each layer’s output.
