A Gradient Boosting Algorithm for Survival Analysis via Direct Optimization of Concordance Index

Survival analysis focuses on modeling and predicting the time to an event of interest. Many statistical models have been proposed for survival analysis. They often impose strong assumptions on hazard functions, which describe how the risk of an event changes over time depending on covariates associa...
