Interpretable Prediction and Feature Selection for Survival Analysis

no code implementations23 Apr 2024 Mike Van Ness, Madeleine Udell

While DyS works well for all survival analysis problems, it is particularly useful for large (in $n$ and $p$) survival datasets such as those commonly found in observational healthcare studies.

Interpretable Survival Analysis for Heart Failure Risk Prediction

no code implementations24 Oct 2023 Mike Van Ness, Tomas Bosschieter, Natasha Din, Andrew Ambrosy, Alexander Sandhu, Madeleine Udell

Specifically, we use an improved version of survival stacking to transform a survival analysis problem to a classification problem, ControlBurn to perform feature selection, and Explainable Boosting Machines to generate interpretable predictions.

The Missing Indicator Method: From Low to High Dimensions

1 code implementation16 Nov 2022 Mike Van Ness, Tomas M. Bosschieter, Roberto Halpin-Gregorio, Madeleine Udell

In this paper, we show empirically and theoretically that MIM improves performance for informative missing values, and we prove that MIM does not hurt linear models asymptotically for uninformative missing values.
