The study of multivariate time series forecasting (MTSF) problems has high signiﬁcance in many areas, such as industrial forecasting and traﬃc ﬂow forecasting. Traditional forecasting models pay more attention to the temporal features of variables, and lack depth in extracting spatial and spatiotemporal features between variables. In this paper, a novel model based on the Transformer, convolutional neural network (CNN) and long short-term memory (LSTM) network is proposed to address the issues. The model ﬁrst extracts the spatial feature vectors through the proposed Multi-Kernel CNN. Then it fully extracts the temporal information by the Encoder layer that consists of the Transformer encoder layer and the LSTM network, which can also obtain the potential spatiotemporal correlation. To extract more feature information, we stack multiple Encoder layers. Finally, the output is decoded by the Decoder layer composed of the ReLU activation function and the Linear layer. To further improve the model’s robustness, we also integrate an autoregressive model. In model evaluation, the proposed model achieves signiﬁcant performance improvements over that of the current benchmark methods for MTSF tasks on two public datasets. Further experiments demonstrate that the model can be used for long horizon forecasting and can also achieve satisfactory results on the yield forecasting of test items (our private dataset, named TIOB).
