Flexible and efficient spatial extremes emulation via variational autoencoders

no code implementations16 Jul 2023 Likun Zhang, Xiaoyu Ma, Christopher K. Wikle, Raphaël Huser

In this paper, we aim to push the boundaries on computation and modeling of high-dimensional spatial extremes via integrating a new spatial extremes model that has flexible and non-stationary dependence properties in the encoding-decoding structure of a variational autoencoder called the XVAE.

Input Perturbation: A New Paradigm between Central and Local Differential Privacy

1 code implementation20 Feb 2020 Yilin Kang, Yong liu, Ben Niu, Xin-Yi Tong, Likun Zhang, Weiping Wang

By adding noise to the original training data and training with the `perturbed data', we achieve ($\epsilon$,$\delta$)-differential privacy on the final model, along with some kind of privacy on the original data.
