How to read the .dat files?

[e1iset]

Thanks for sharing this novel approach to study the material properties. I'm a beginner at the neural network and have some stupid questions about how to read the .dat files outputted from nn.py code.

1. In test.dat and train.dat, why the x values are not the same as the ones in the .csv files?
2. There are 2 columns of y values, as well as two columns of predicted y values, what's the purpose of having two columns of the same type of data?
3. In the experiment data, the elastoplastic properties are measured from each test or referred from a tenable value of the same material?

1. The data is normalized for training.
2. One is from low-fidelity NN, and the other one is from high-fidelity NN.
3. The properties are measured from each material.
