Multi-objective evolutionary GAN for tabular data synthesis

1 code implementation15 Apr 2024 Nian Ran, Bahrul Ilmi Nasution, Claire Little, Richard Allmendinger, Mark Elliot

However, there are unique challenges in tabular data compared to images, eg tabular data may contain both continuous and discrete variables and conditional sampling, and, critically, the data should possess high utility and low disclosure risk (the risk of re-identifying a population unit or learning something new about them), providing an opportunity for multi-objective (MO) optimization.

Comparing the Utility and Disclosure Risk of Synthetic Data with Samples of Microdata

1 code implementation2 Jul 2022 Claire Little, Mark Elliot, Richard Allmendinger

The paper presents a framework to measure the utility and disclosure risk of synthetic data by comparing it to samples of the original data of varying sample fractions, thereby identifying the sample fraction which has equivalent utility and risk to the synthetic data.

Provenance, Anonymisation and Data Environments: a Unifying Construction

no code implementations21 Jul 2021 Muhammad Aslam Jarwar, Adriane Chapman, Mark Elliot, Fatemeh Raji

Based on this use case, we identify how provenance information could be utilized within the ADF framework, and identify a currently un-met requirement which is the modeling of \textit{data environments}.

Breaking the Activation Function Bottleneck through Adaptive Parameterization

1 code implementation NeurIPS 2018 Sebastian Flennerhag, Hujun Yin, John Keane, Mark Elliot

Standard neural network architectures are non-linear only by virtue of a simple element-wise activation function, making them both brittle and excessively large.
