Preprocessing

Using the formula from ChebyNet：

Model structure

Differents of code between mine and author's

  1. Fix bugs
  2. Add Early Stopping approach
  3. Add Dropout approach
  4. Offer a different set of hyperparameters
  5. Offer config files for two different categories graph convolution (ChebyGraphConv and GraphConv)
  6. Add datasets METR-LA and PEMS-BAY
  7. Adopt a different data preprocessing method
