[Experiment] Try to train models for enhancement

## Guide
- Try to run the whole project codes without any error with the latest version.
- There are four versions of model. You can try to modify their `Model Parameters` and train/evaluate the model.
- If you willing to construct the model from zero, that's would be nice try!

Start by running the whole project with the latest version and confirm whether it completes without errors. Then inspect the four model versions and their `Model Parameters` sections before trying training and evaluation. Done means the project runs successfully and the selected model experiments produce documented training and evaluation results.
