NN on eFEDS observed data: comparison of WL calibrated mass estimates (using luminosity scaling relations as in Eq. (67) of Chiu et al. 2022) and masses obtained from our ensemble neural networks. Left: respective mass predictions on eFEDS clusters. The uncertainties on the mass predictions are color-coded and correspond to the NN uncertainties. Right: correlation between predicted masses on eFEDS observations and the measured luminosities as presented in Chiu et al. (2022).
