The ... WebMar 14, 2024 · The time interval of two items determines the weight of each edge in the graph. Then the item model combined with the time interval information is obtained through the Graph Convolutional Networks (GCN). Finally, the self-attention block is used to adaptively compute the attention weights of the items in the sequence.
