Model Survival Data with high and ultrahigh dimensional predictors: feature screening and statistical inference - Lecture 2

Overview

Abstract

Continuing on with Lecture 1,  this short course introduces various cutting-edge methods that handle survival outcome data with ultrahigh dimensional predictors, that is when the dimension of predictors is much higher than the sample size. We will also discuss several new methods for quantifying the uncertainty of estimates in a high-dimensional survival setting, a very active area in machine learning.  

The specific topics include.

Feature screening with ultra-high dimensional predictors (p>>n):

1. Principled sure independent screening (PSIS),
2. Conditional screening,
3. IPOD,
4. Forward selection, etc;

Inference for survival models with high dimensional predictors (p>n).
