Abstract

Abstract

Water demand forecasting is the basis of the optimization of water networks, and its accuracy is important for the following work. Graph neural network, an emerging architect, takes advantage of the topological information to enhance the learning results, which means the topology of the water network can an input feature of the graph-based neural network model and lift the prediction accuracy. This work tried to utilize Graph Wavenet model in water demand forecasting and make use of the topological feature of the water network. After utilizing real-world history data in the training process, the average 5 min prediction MAPE error result was 1.28%. Besides, this experiment showed that Graph Wavenet raised the prediction accuracy, compared to WaveNet without graph convolution operation, confirming the contribution of the graph convolution mechanism. This work also talked about future applications of GNN on water distribution networks.
