Description
In lattice QCD simulations, a large number of observables are calculated on each Monte Carlo sample of gauge fields, and their statistical fluctuations are correlated with each other as they share the same background gauge field. By exploiting the correlation, a machine learning regression model can be trained to predict the values of the computationally expensive observables from the values of the computationally cheap observables for each Monte Carlo sample of the gauge field. I will present the machine learning algorithm and its applications to the prediction of lattice QCD observables and discuss the bias correction and error quantification procedure of the machine learning predictions on statistical data.
