Researchers have introduced FLEXI-Haz, a novel deep neural network framework designed for survival data analysis with a partially linear regression structure. This method distinguishes itself by maintaining interpretability through a parametric linear component while employing a nonparametric DNN to capture complex interactions among nuisance variables. Notably, FLEXI-Haz does not rely on the proportional hazards assumption, a common limitation in existing models. The framework offers theoretical guarantees, including optimal convergence rates for the neural network and efficient estimation for the linear component, along with asymptotic confidence intervals for survival functions.
