Outline

In this paper, we propose a new model that utilizes the potential of Convolutional Neural Network (CNN), considering the research trend that mainly relies on Transformer and MLP models in the existing long-term time series forecasting. We introduce a multi-scale time series reconstruction module that effectively captures the relationship between patches of different periods and the dependency between variables, and propose MS-TVNet, a multi-scale 3D dynamic CNN based on it. Experimental results on various datasets show that MS-TVNet outperforms existing models and achieves state-of-the-art (SOTA) results in long-term time series forecasting. This demonstrates the effectiveness of utilizing CNN to capture complex temporal patterns and suggests promising directions for future research in this field.
