  Quantum chromodynamics (QCD) is the theory of the strong interaction. The
fundamental particles of QCD, quarks and gluons, carry colour charge and form
colourless bound states at low energies. The hadronic bound states of primary
interest to us are the mesons and the baryons. From knowledge of the meson
spectrum, we use neural networks and Gaussian processes to predict the masses
of baryons with 90.3% and 96.6% accuracy, respectively. These results compare
favourably to the constituent quark model. We as well predict the masses of
pentaquarks and other exotic hadrons.
