Masked Language Modeling Becomes Conditional Density Estimation for Tabular Data Synthesis

no code implementations31 May 2024 SeungHwan An, Gyeongdong Woo, Jaesung Lim, Changhyun Kim, Sungchul Hong, Jong-June Jeon

Given that the MLu performance relies on accurately approximating the conditional distributions, we focus on devising a synthetic data generation method based on conditional distribution estimation.

Improving SMOTE via Fusing Conditional VAE for Data-adaptive Noise Filtering

no code implementations30 May 2024 Sungchul Hong, SeungHwan An, Jong-June Jeon

We investigate the problem of the generative model for imbalanced classification and introduce a framework to enhance the SMOTE algorithm using Variational Autoencoders (VAE).

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.

Uniform Pessimistic Risk and its Optimal Portfolio

no code implementations2 Mar 2023 Sungchul Hong, Jong-June Jeon

However, estimating an optimal portfolio assessed by a pessimistic risk is still challenging due to the absence of a computationally tractable model.
