leave two tasks

Today, I improved all other parts except two tasks.

Summary:

Two tasks:

1. Evaluation of NRMSE and R2 and their explanation

2. Train and test the third method in well 1 and apply it in well 2 and vice versa

Next week, I will try to find good explanation of NRMSE and R2 and realize the application of the third method in 2 wells.
