North or South? Diagnosing LLMs' Understanding of North Korean Language, Society, and Knowledge
Kiwoong Park, Seyoung Song, Donghyun Woo +1
Large Language Models (LLMs) have made substantial progress in multilingual question answering, yet their ability to understand low-resource sociolinguistic contexts remains under-…
The Surrogate Is Not the Reward: Post-Surrogate Primary-Outcome Acquisition in Contextual Bandits
Kyungbok Lee, Michael R. Kosorok
We study contextual bandits in which a surrogate is observed after the action but before the learner decides whether to acquire the primary outcome that defines action value and re…
Discussion of Multiscale Fisher's Independence Test for Multivariate Dependence
Duyeol Lee, Helal El-Zaatari, Michael R. Kosorok +2
The multiscale Fisher's independence test (MULTIFIT hereafter) proposed by Gorsky & Ma (2022) is a novel method to test independence between two random vectors. By its design, this…
Stabilized Direct Learning for Efficient Estimation of Individualized Treatment Rules
Kushal S. Shah, Haoda Fu, Michael R. Kosorok
In recent years, the field of precision medicine has seen many advancements. Significant focus has been placed on creating algorithms to estimate individualized treatment rules (IT…
A unified nonparametric fiducial approach to interval-censored data
Yifan Cui, Jan Hannig, Michael Kosorok
Censored data, where the event time is partially observed, are challenging for survival probability estimation. In this paper, we introduce a novel nonparametric fiducial approach…
Multi-stage optimal dynamic treatment regimes for survival outcomes with dependent censoring
Hunyong Cho, Shannon T. Holloway, David J. Couper +1
We propose a reinforcement learning method for estimating an optimal dynamic treatment regime for survival outcomes with dependent censoring. The estimator allows the failure time…
