 - `--weight-decay` and `--hidden-dropout` are for stage 1. `--weight-decay2` and `--hidden-dropout2` are for stage 2.
 - The learning rate for stage 1 is `--init-learningrate`. The learning rate for stage 2 is the product of `--init-learningrate` and `--all-layer-multiplier`.
 
+## Computational environment
+The research in this study is carried out on a Linux workstation with 8 CPU cores and a single NVIDIA Quadro M4000 GPU with 8GB memory. The deep learning framework is Keras 2 with Tensorflow as the backend.
