Enhancing the Locality and Breaking the Memory …
One of the most prominent models is ARIMA [15]. Its statistical properties as well as the well-known Box-Jenkins methodology [16] in the model selection procedure make it the first attempt for practitioners. However, its linear assumption and limited scalability make it unsuitable for large-scale forecasting tasks.

Generative Adversarial Imitation Learning

We test our algorithm in Section 6, where
