Training an artificial neural network for recognizing electron collision patterns

Electron scattering cross sections have been acquired both theoretically and experimentally over the last few decades. By combining scattering data with machine learning, this work is designed to provide physics benefits: AI assisted incorrect-data screening, cross section data generation, and inverse design. As a basic task before undertaking these applications, we present essential training procedures in this paper. We trained electron-collision data to train a neural network with the type of each collision. The neural network with two hidden layer was implemented using multilayer perceptrons, the earliest deep learning model. Monte Carlo cross-validation was employed to ensure the reliability of the test results, and the optimal model structure was obtained by performing Bayesian optimization. We evaluated our model through the performance indicators within a confidence interval. The results indicate that the data were well-learned, except for the attachment class. Furthermore, feature investigation was carried out to ensure the decision-making process.
