Abstract: Causal inference permits us to discover covert relationships of various variables in time series. However, in most exist- ing works, the variables mentioned above are the dimensions. The causality between dimensions could be cursory, which hinders the comprehension of the internal relationship and the benefit of the causal graph to the neural networks (NNs). In this paper, we find that causality exists not only outside but also inside the time series because it implies the succession of events in the real world. It inspires us to seek the relation- ship between internal subsequences. However, the challenges are the hardship of discovering causality from subsequences and utilizing the causal natural structures to improve Neural Networks. To address these challenges, we propose a novel framework called Mining Causal Natural Structure (MCNS ), which is automatic and domain-agnostic and helps to find the causal natural structures inside time series via the inter- nal causality scheme. We evaluate the MCNS framework and integrate NN with MCNS on time series classification tasks. Experimental results illustrate that our impregnation, by re- fining attention, shape selection classification, and pruning datasets, drives NN, even the data itself preferable accuracy and interpretability. Besides, MCNS provides an in-depth, solid summary of the time series and datasets.
