DR-VIDAL -- Doubly Robust Variational Information-theoretic Deep Adversarial Learning for Counterfactual Prediction and Treatment Effect Estimation on Real World Data

1 code implementation7 Mar 2023 Shantanu Ghosh, Zheng Feng, Jiang Bian, Kevin Butler, Mattia Prosperi

DR-VIDAL integrates: (i) a variational autoencoder (VAE) to factorize confounders into latent variables according to causal assumptions; (ii) an information-theoretic generative adversarial network (Info-GAN) to generate counterfactuals; (iii) a doubly robust block incorporating treatment propensities for outcome predictions.

BatmanNet: Bi-branch Masked Graph Transformer Autoencoder for Molecular Representation

1 code implementation25 Nov 2022 Zhen Wang, Zheng Feng, Yanjun Li, Bowen Li, Yongrui Wang, Chulin Sha, Min He, Xiaolin Li

Although substantial efforts have been made using graph neural networks (GNNs) for AI-driven drug discovery (AIDD), effective molecular representation learning remains an open challenge, especially in the case of insufficient labeled molecules.

Variational Temporal Deconfounder for Individualized Treatment Effect Estimation from Longitudinal Observational Data

no code implementations23 Jul 2022 Zheng Feng, Mattia Prosperi, Jiang Bian

Estimating treatment effects, especially individualized treatment effects (ITE), using observational data is challenging due to the complex situations of confounding bias.

Generalized Batch Normalization: Towards Accelerating Deep Neural Networks

no code implementations8 Dec 2018 Xiaoyong Yuan, Zheng Feng, Matthew Norton, Xiaolin Li

Utilizing recently introduced concepts from statistics and quantitative risk management, we present a general variant of Batch Normalization (BN) that offers accelerated convergence of Neural Network training compared to conventional BN.

GraphBTM: Graph Enhanced Autoencoded Variational Inference for Biterm Topic Model

1 code implementation EMNLP 2018 Qile Zhu, Zheng Feng, Xiaolin Li

In this paper, we propose a novel way called GraphBTM to represent biterms as graphs and design a Graph Convolutional Networks (GCNs) with residual connections to extract transitive features from biterms.
