Machine Learning for predicting the evolution of supermassive black hole binariesPulsar Timing Arrays detect the stochastic gravitational wave background from supermassive black hole binaries (BHBs), requiring accurate merger timescales for astrophysical insights. Machine learning techniques, such as neural ordinary differential equations and symbolic regression, are proposed to improve BHB evolution modeling by interpolating noisy orbital elements and reducing simulation times. These methods enhance merger timescale predictions, aiding in GWB interpretation.
