SPATE-GAN: Improved Generative Modeling of Dynamic Spatio-Temporal Patterns with an Autoregressive Embedding Loss

1 code implementation30 Sep 2021 Konstantin Klemmer, Tianlin Xu, Beatrice Acciaio, Daniel B. Neill

In this study, we propose a novel loss objective combined with COT-GAN based on an autoregressive embedding to reinforce the learning of spatio-temporal dynamics.

Double Generative Adversarial Networks for Conditional Independence Testing

1 code implementation3 Jun 2020 Chengchun Shi, Tianlin Xu, Wicher Bergsma, Lexin Li

In this article, we study the problem of high-dimensional conditional independence testing, a key building block in statistics and machine learning.

Variational f-divergence Minimization

no code implementations27 Jul 2019 Mingtian Zhang, Thomas Bird, Raza Habib, Tianlin Xu, David Barber

Probabilistic models are often trained by maximum likelihood, which corresponds to minimizing a specific f-divergence between the model and data distribution.

Training generative latent models by variational f-divergence minimization

no code implementations27 Sep 2018 Mingtian Zhang, Thomas Bird, Raza Habib, Tianlin Xu, David Barber

Probabilistic models are often trained by maximum likelihood, which corresponds to minimizing a specific form of f-divergence between the model and data distribution.
