Figure 5. Photon energy prediction in a double-pulse mode.

(a) A sample of a double-pulse spectrum measured with the electron time-of-flight spectrometer (light red) and the corresponding double Gaussian fit (thick red). (b,c) Measured photon energies of each of the pulses compared to the predicted photon energies for the test set using an artificial neural network. Experimental points are shown in blue. The perfect correlation lines are included for reference as black dashed lines. Mean error of predictions: 0.46 and 0.40 eV, respectively. Mean error of initial distributions: 1.45 and 1.03 eV, respectively.
