Tensor time series TTS data a generalization of one dimensional time series on a high dimensional space is ubiquitous in real world scenarios especially in monitoring systems involving multi source spatio temporal data e g transportation demands and air pollutants Compared to modeling time series or multivariate time series which has received much attention and achieved tremendous progress in recent years tensor time series has been paid less effort Properly coping with the tensor time series is a much more challenging task due to its high dimensional and complex inner structure In this paper we develop a novel TTS forecasting framework which seeks to individually model each heterogeneity component implied in the time the location and the source variables We name this framework as GMRL short for Gaussian Mixture Representation Learning Experiment results on two real world TTS datasets verify the superiority of our approach compared with the state of the art baselines Code and data are published on https github com beginner sketch GMRL 2023 International Joint Conferences on Artificial Intelligence All rights reserved
