Ab initio many-body methods\, such as many-body perturbat ion theory and coupled cluster theory\, can provide accurate calculations f or infinite nuclear matter by considering the system from its individual pa rticles and the forces at play between them. However\, these calculations c an suffer from very long run times and thus prevent large-scale studies. Th is work presents a set of algorithms based on Bayesian machine learning\, w hich can drastically reduce the run times needed for ab initio calculations of infinite nuclear matter systems by predicting the values of the calcula tions from smaller\, faster-running calculations. This work focuses on remo ving the basis truncation error from coupled cluster calculations by predic ting the converged energies from calculations at smaller basis sizes and pr edicting the energy from a many-body perturbation calculation to the fourth order\, using results from lower-order calculations. Both accuracy and tim e savings will be considered motivations for these Bayesian machine learnin g methods.
