Wasserstein Geodesic Generator for Conditional Distributions

1 code implementation20 Aug 2023 Young-geun Kim, Kyungbok Lee, Youngwon Choi, Joong-Ho Won, Myunghee Cho Paik

The conditional distributions given unobserved intermediate domains are on the Wasserstein geodesic between conditional distributions given two observed domain labels.

Covariate-informed Representation Learning to Prevent Posterior Collapse of iVAE

no code implementations9 Feb 2022 Young-geun Kim, Ying Liu, XueXin Wei

Though the identifiability is appealing, we show that iVAEs could have local minimum solution where observations and the approximated ICs are independent given covariates.-a phenomenon we referred to as the posterior collapse problem of iVAEs.

Kernel-convoluted Deep Neural Networks with Data Augmentation

1 code implementation4 Dec 2020 Minjin Kim, Young-geun Kim, Dongha Kim, Yongdai Kim, Myunghee Cho Paik

The Mixup method (Zhang et al. 2018), which uses linearly interpolated data, has emerged as an effective data augmentation tool to improve generalization performance and the robustness to adversarial examples.
