Description: ¹ RMSE, root mean square error; ² LOSpred, predicted length of stay; ³ ERRpred, predicted error; ^4–6 Dispred_Loss1-3, prediction of the LOS range using the probability distribution with loss function 1–3; ⁷ WGAN-GP for LOS, wasserstein generative adversarial network with a gradient penalty for the length of stay; ⁸ STDpred, predicted standard deviation.
