MISNN: Multiple Imputation via Semi-parametric Neural Networks

no code implementations2 May 2023 Zhiqi Bu, Zongyu Dai, Yiliang Zhang, Qi Long

Multiple imputation (MI) has been widely applied to missing value problems in biomedical, social and econometric research, in order to avoid improper inference in the downstream data analysis.

Multiple Imputation with Neural Network Gaussian Process for High-dimensional Incomplete Data

1 code implementation23 Nov 2022 Zongyu Dai, Zhiqi Bu, Qi Long

Single imputation methods such as matrix completion methods do not adequately account for imputation uncertainty and hence would yield improper statistical inference.

Multiple Imputation via Generative Adversarial Network for High-dimensional Blockwise Missing Value Problems

no code implementations21 Dec 2021 Zongyu Dai, Zhiqi Bu, Qi Long

Missing data are present in most real world problems and need careful handling to preserve the prediction accuracy and statistical consistency in the downstream analysis.

On the Convergence and Calibration of Deep Learning with Differential Privacy

1 code implementation15 Jun 2021 Zhiqi Bu, Hua Wang, Zongyu Dai, Qi Long

Differentially private (DP) training preserves the data privacy usually at the cost of slower convergence (and thus lower accuracy), as well as more severe mis-calibration than its non-private counterpart.
