Improved feature selection with simulation optimization
Shashaani, S., & Vahdat, K. (2022, May 30). OPTIMIZATION AND ENGINEERING, Vol. 5.
author keywords: Stochastic error analysis; Adaptive sampling; Predictive accuracy; Data-driven dependence; Reliability
TL;DR:
This work develops adaptive sampling strategies for large enough datasets, where the number of training and test resamples vary for each solution, and develops adaptive sample sizes, which reach the same quality level of recommended feature subsets but significantly faster than the fixed sample size version.

2022 conference paper
Personalized Predictions for Unplanned Urinary Tract Infection Hospitalizations with Hierarchical Clustering
Springer Proceedings in Business and Economics, 453–465.
TL;DR:
A hierarchical clustering approach that leverages existing knowledge and data-driven algorithms to partition the population into groups of similar risk, followed by building a LASSO-Logistic Regression model for each group, achieves more accurate and precise predictions and offers more granular feature importance insights for each patient group.

2020 article
SIMULATION OPTIMIZATION BASED FEATURE SELECTION, A STUDY ON DATA-DRIVEN OPTIMIZATION WITH INPUT UNCERTAINTY
2020 WINTER SIMULATION CONFERENCE (WSC), pp. 2149–2160.
TL;DR:
This work proposes a framework for simulation optimization over a high dimensional binary space in place of the classic greedy search in forward or backward selection or regularization methods, and provides insight for leveraging Monte Carlo methodology in probabilistic data-driven modeling and analysis.
