Average RMSE for the vDNN model as the numbers of input nodes are varied. (a) Average RMSE of the three parameters, \(\omega _c\), \(\omega _a\), and g. (b) RMSE of the energy spectrum. Triangles (squares) denote results using the feature \(\Delta e\) (\(\Delta e^2\)). Lines connecting the data points are drawn to aid the eye.
