Efficiently learns Gaussian distributions from censored data with known missingness patterns.

problem Learning high-dimensional Gaussian distributions from data with missing values.
method Developed algorithms for self-censoring and linear thresholding scenarios.
result Achieved efficient learning of Gaussian distributions up to a specified total variation distance.

The paper introduces tests for missing data models based on graph assumptions.

problem Verification of assumptions in missing data models is insufficiently addressed.
method The paper explores three classes of missing data models and designs goodness-of-fit tests.
result The paper provides new insights and tests for missing data graphical models.

Deep learning for missing data with flexible modelling.

problem Missing data with missingness dependent on the missing values.
method Deep latent variable models with a neural network for missingness pattern modeling, importance-weighted variational inference, and stochastic gradients.
result Explicitly modelling missingness improves inference on various data sets.

This paper presents a method to generate synthetic data with differential privacy to protect user privacy while maintaining data trends.

problem Protecting user privacy while using real data for AI applications.
method Develops a practical guide to generating synthetic data using differential privacy.
result Synthetic data can be generated to preserve trends of real data while ensuring strong privacy protections.
