RATL

This code is the implementation of the paper "A Relationship-Aligned Transfer Learning Algorithm for Time Series Forecasting".
Instruction on the code:

• Training base encoder and regressor
  Once the data preparation is completed, we can train the base encoder and regressor for it.
  cd dataset; python train.py --lr1 0.1 --train_epochs1 200 --window 1 --neg_samples 10 --compared length None --compute_linear True

• Transfer
  Once the source and target encoders and regressors are trained, we can implement the transfer phase. Separately run stage_1 and stage_2 in RATL.py
  cd transfer; python RATL.py --mode_1 False --train_epochs2 1000 --compute_2 True --mode_2 True --encode_pred_num 1 --encode_window 56 --test_pred_term 56

• loda model
  After traning and transfer phases, we can load the saved models to predict the test data
  cd transfer; python get_encoder_linear.py

We run this code on cpu, you can change it according to the configuration.
