Association between Sitting Time and Urinary Incontinence in the US Population: data from the National Health and Nutrition Examination Survey (NHANES) 2007 to 2018

no code implementations8 Feb 2024 Guanbo Wang, Xingpeng Di

Compared with patients with sitting time shorter than 7 hours, moderate activity increased the risk of prolonged sitting time over 7 hours in the fully-adjusted model (OR = 2. 537, 95% CI = 1. 419 to 4. 536, P = 0. 002).

CLARE: Conservative Model-Based Reward Learning for Offline Inverse Reinforcement Learning

no code implementations9 Feb 2023 Sheng Yue, Guanbo Wang, Wei Shao, Zhaofeng Zhang, Sen Lin, Ju Ren, Junshan Zhang

This work aims to tackle a major challenge in offline Inverse Reinforcement Learning (IRL), namely the reward extrapolation error, where the learned reward function may fail to explain the task correctly and misguide the agent in unseen environments due to the intrinsic covariate shift.

A Fault Location Method Using Direct Convolution: Electromagnetic Time Reversal or Not Reversal

no code implementations27 Nov 2021 Guanbo Wang, Chijie Zhuang

The faults can be located efficiently via direct convolution of the signal collected from a fault and the pre-stored calculated transients, even using a fraction of the fault signal.

Modeling Treatment Effect Modification in Multidrug-Resistant Tuberculosis in an Individual Patient Data Meta-Analysis

no code implementations11 Jan 2021 Yan Liu, Mireille Schnitzer, Guanbo Wang, Edward Kennedy, Piret Viiklepp, Mario H. Vargas, Giovanni Sotgiu, Dick Menzies, Andrea Benedetti

We propose a marginal structural model (MSM) for effect modification by different patient characteristics and co-medications in a meta-analysis of observational IPD.
