Spatiotemporal Self-Attention-Based LSTNet for Multivariate Time Series Prediction

چکیده
Multivariate time series prediction is a critical problem that encountered in many fields, and recurrent neural network (RNN)-based approaches have been widely used to address this problem. However, traditional RNN-based for predicting multivariate are still facing challenges, as often related each other historical observations real-world applications. To limitation, paper proposes spatiotemporal self-attention mechanism-based LSTNet, which forecasting model. The proposed model leverages two strategies, spatial temporal self-attention, focus on the most relevant information among series. discover dependences between variables, while attention employed capture relationship observations. Moreover, standard deviation term added objective function track effectively. evaluate method’s performance, extensive experiments conducted multiple benchmarked datasets. experimental results show method outperforms several baseline methods significantly. Therefore, self-attention-based LSTNet promising approach

Multivariate Time Series Prediction via Temporal Classification
One of the important problems in many process industries is how to predict the occurrence of abnormal situations ahead of time in a multivariate time series environment. For example, in an oil refinery, hundreds of sensors (process variables) are installed at different sections of a process unit. These sensors constantly monitor the development of every stage of the process. Typically, each pro...
متن کاملSome New Methods for Prediction of Time Series by Wavelets
Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...

متن کاملTime Series Based Link Prediction
Link prediction is a task in Social Network Analysis that consists of predicting connections that are most likely to appear considering previous observed links in a social network. The majority of works in this area only performs the task by exploring the state of the network at a specific moment to make the prediction of new links, without considering the behavior of links as time goes by. In ...
