Scalable Community Extraction of Text Networks for Automated Grouping in Medical Databases
Journal of Data Science.
TL;DR:
A well-known community extraction method is adapted to develop a scalable algorithm for extracting groups of similar documents in large text databases and it is demonstrated that the groups generated from community extraction are much more accurate than manual tagging by frontline workers.

A PRticle filter algorithm for nonparametric estimation of multivariate mixing distributions
STATISTICS AND COMPUTING, 33(4).
author keywords: Importance sampling; Marked point process; Mixture model; Monte Carlo; Predictive recursion
TL;DR:
A new strategy is proposed, which is referred to as PRticle filter, wherein the basic PR algorithm is augmented with a filtering mechanism that adaptively reweights an initial set of particles along the updating sequence which are used to obtain Monte Carlo approximations of the normalizing constants.

Targeted optimal treatment regime learning using summary statistics
Chu, J., Lu, W., & Yang, S. (2023, March 15). BIOMETRIKA, Vol. 3.
author keywords: Covariate shift; Double robustness; Empirical likelihood; Entropy balancing; Multisource policy learning
TL;DR:
This work proposes a calibrated augmented inverse probability weighted estimator of the value function for the target population and estimates an optimal treatment regime by maximizing this estimator within a class of pre-specified regimes and develops a weighting framework that tailors a treatment regime for a given target population by leveraging the available summary statistics.

Deep spectral Q-learning with application to mobile health
STAT, 12(1).
author keywords: dynamic treatment regimes; mixed frequency data; principal component analysis; reinforcement learning
TL;DR:
A deep spectral Q‐learning algorithm is proposed, which integrates principal component analysis (PCA) with deep Q‐learning to handle the mixed frequency data and proves that the mean return under the estimated optimal policy converges to that under the optimal one and establishes its rate of convergence.
