Flexible and efficient spatial extremes emulation via variational autoencoders

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

Many real-world processes have complex tail dependence structures that cannot be characterized using classical Gaussian processes.

Deep Integro-Difference Equation Models for Spatio-Temporal Forecasting

1 code implementation29 Oct 2019 Andrew Zammit-Mangion, Christopher K. Wikle

Both procedures tend to be excellent for prediction purposes over small time horizons, but are generally time-consuming and, crucially, do not provide a global prior model for the temporally-varying dynamics that is realistic.

Comparison of Deep Neural Networks and Deep Hierarchical Models for Spatio-Temporal Data

no code implementations22 Feb 2019 Christopher K. Wikle

This overview paper presents a brief introduction to the deep hierarchical DSTM (DH-DSTM) framework, and deep models in machine learning, culminating with the deep neural DSTM (DN-DSTM).

Deep Echo State Networks with Uncertainty Quantification for Spatio-Temporal Forecasting

no code implementations28 Jun 2018 Patrick L. McDermott, Christopher K. Wikle

The methodology is first applied to a data set simulated from a novel non-Gaussian multiscale Lorenz-96 dynamical system simulation model and then to a long-lead United States (U. S.) soil moisture forecasting application.

Bayesian Recurrent Neural Network Models for Forecasting and Quantifying Uncertainty in Spatial-Temporal Data

no code implementations2 Nov 2017 Patrick L. McDermott, Christopher K. Wikle

Recurrent neural networks (RNNs) are nonlinear dynamical models commonly used in the machine learning and dynamical systems literature to represent complex dynamical or sequential relationships between variables.
