Balanced Marginal and Joint Distributional Learning via Mixture Cramer-Wold Distance

no code implementations6 Dec 2023 SeungHwan An, Sungchul Hong, Jong-June Jeon

This measure enables us to capture both marginal and joint distributional information simultaneously, as it incorporates a mixture measure with point masses on standard basis vectors.

Joint Distributional Learning via Cramer-Wold Distance

no code implementations25 Oct 2023 SeungHwan An, Jong-June Jeon

The assumption of conditional independence among observed variables, primarily used in the Variational Autoencoder (VAE) decoder modeling, has limitations when dealing with high-dimensional datasets or complex correlation structures among observed variables.

Causally Disentangled Generative Variational AutoEncoder

1 code implementation23 Feb 2023 SeungHwan An, Kyungwoo Song, Jong-June Jeon

We present a new supervised learning technique for the Variational AutoEncoder (VAE) that allows it to learn a causally disentangled representation and generate causally disentangled outcomes simultaneously.

Distributional Learning of Variational AutoEncoder: Application to Synthetic Data Generation

1 code implementation NeurIPS 2023 SeungHwan An, Jong-June Jeon

The Gaussianity assumption has been consistently criticized as a main limitation of the Variational Autoencoder (VAE) despite its efficiency in computational modeling.

EXoN: EXplainable encoder Network

1 code implementation23 May 2021 SeungHwan An, Hosik Choi, Jong-June Jeon

To improve the performance of our VAE in a classification task without the loss of performance as a generative model, we employ a new semi-supervised classification method called SCI (Soft-label Consistency Interpolation).
