KG-TREAT: Pre-training for Treatment Effect Estimation by Synergizing Patient Data with Knowledge Graphs

1 code implementation6 Mar 2024 Ruoqi Liu, Lingfei Wu, Ping Zhang

To address the challenges, we introduce a novel pre-training and fine-tuning framework, KG-TREAT, which synergizes large-scale observational patient data with biomedical knowledge graphs (KGs) to enhance TEE.

Deconfounding Actor-Critic Network with Policy Adaptation for Dynamic Treatment Regimes

1 code implementation19 May 2022 Changchang Yin, Ruoqi Liu, Jeffrey Caterino, Ping Zhang

Although some treatment actions non-survivors received may be helpful, if confounders cause the mortality, the training of RL models guided by long-term outcomes (e. g., 90-day mortality) would punish those treatment actions causing the learned DTR policies to be suboptimal.

Estimating Individual Treatment Effects with Time-Varying Confounders

1 code implementation27 Aug 2020 Ruoqi Liu, Changchang Yin, Ping Zhang

Estimating the individual treatment effect (ITE) from observational data is meaningful and practical in healthcare.

When deep learning meets causal inference: a computational framework for drug repurposing from real-world data

1 code implementation16 Jul 2020 Ruoqi Liu, Lai Wei, Ping Zhang

Drug repurposing is an effective strategy to identify new uses for existing drugs, providing the quickest possible transition from bench to bedside.
