Censored Quantile Regression Neural Networks for Distribution-Free Survival Analysis. (arXiv:2205.13496v2 [stat.ML] UPDATED)
cs.LG updates on arXiv.org arxiv.org
This paper considers doing quantile regression on censored data using neural
networks (NNs). This adds to the survival analysis toolkit by allowing direct
prediction of the target variable, along with a distribution-free
characterisation of uncertainty, using a flexible function approximator. We
begin by showing how an algorithm popular in linear models can be applied to
NNs. However, the resulting procedure is inefficient, requiring sequential
optimisation of an individual NN at each desired quantile. Our major
contribution is a novel algorithm …
