Monthly Notices of the Royal Astronomical Society, 528(4), 6354-6369. https://doi.org/10.1093/mnras/stae406Conventional galaxy mass estimation methods suffer from model assumptions and degeneracies. Machine learning (ML), which reduces the reliance on such assumptions, can be used to determine how well present-day observations can yield predictions for th...
