In this paper, we provide two novel regression-based integrations of combined
regression strategy (COBRA) ensemble using Integrated Brier Score to predict
conditional survival function. Our proposition includes a weighted version of
all predictions based on Integrated Brier Score score made by all weak learners
to predict the final survival function apart from the straight implementation.
Two different norms (Frobenius and Sup norm) used to figure out the proximity
points in the algorithm. Our implementations consider right-censored data too.
We illustrate …
