  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 norm) to extract the proximity
points in the algorithm. Our implementations consider right-censored data too.
We illustrate the proposed algorithms through some real-life data analysis.
