Predicting Exotic Hadron Masses with Data Augmentation Using Multilayer Perceptron

Recently, there have been significant developments in neural networks; thus, neural networks have been frequently used in the physics literature. This work estimates the masses of exotic hadrons, doubly charmed and bottomed baryons from the meson and baryon masses using neural networks. Subsequently, the number of data has been increased using the artificial data augmentation technique proposed recently. We have observed that the neural network's predictive ability increases using augmented data. This study has shown that data augmentation techniques play an essential role in improving neural network predictions; moreover, neural networks can make reasonable predictions for exotic hadrons, doubly charmed, and doubly bottomed baryons. The results are also comparable to Gaussian Process and Constituent Quark Model.
