New computational algorithms make it possible to build neural networks with many input nodes and many layers, and distinguish "deep learning" of these networks from previous work on artificial neural nets.
We thank all the reviewers for providing valuable feedback. In what follows, we address specific questions. The main motivation is computational. We will discuss this motivation in Section 2.1. Q2 (R2): Metrics or experiments to assess whether the model is overfitting or memorizing the dataset.
