Integrated Brier Score based Survival Cobra -- A regression based approach. (arXiv:2210.12006v2 [cs.LG] UPDATED)

Recently Goswami et al. \cite{goswami2022concordance} introduced two novel
implementations of combined regression strategy to find the conditional
survival function. The paper uses regression-based weak learners and provides
an alternative version of the combined regression strategy (COBRA) ensemble
using the Integrated Brier Score to predict conditional survival function. We
create a novel predictor based on a weighted version of all machine predictions
taking weights as a specific function of normalized Integrated Brier Score. We
use two different norms (Frobenius and Sup …
