چکیده

Spatial and spatio-temporal processes are often described with a Gaussian process model. This model can be represented as a convolution of a white noise process and a smoothing kernel. We expand upon this model by considering convolutions of non-iid background processes. We highlight two particular models based on convolutions of Markov random fields and of time-varying processes. These models are illustrated using examples from hydrology and atmospheric science.

Multi-class Classification with Dependent Gaussian Processes

We present a novel multi-output Gaussian process model for multi-class classification. We build on the formulation of Gaussian processes via convolution of white Gaussian noise processes with a parameterized kernel and present a new class of multi-output covariance functions. The latter allow for greater flexibility in modelling relationships between outputs while being parsimonious with regard...

Bayesian Alignments of Warped Multi-Output Gaussian Processes

We present a Bayesian extension to convolution processes which defines a representation between multiple functions by an embedding in a shared latent space. The proposed model allows for both arbitrary alignments of the inputs and and also non-parametric output warpings to transform the observations. This gives rise to multiple deep Gaussian process models connected via latent generating proces...

Modelling Non-stationary and Non-separable Spatio-Temporal Changes in Neurodegeneration via Gaussian Process Convolution

Modelling longitudinal changes in organs is fundamental for the understanding of biological and pathological processes. Most of the previous works on spatio-temporal modelling of image time series relies on the assumption of stationarity of the local spatial correlation, and on the separability between spatial and temporal processes. These assumptions are often made in order to lead to computat...

Local Likelihood Estimation for Covariance Functions with Spatially-Varying Parameters: The convoSPAT Package for R

In spite of the interest in and appeal of convolution-based approaches for nonstationary spatial modeling, off-the-shelf software for model fitting does not as of yet exist. Convolution-based models are highly flexible yet notoriously difficult to fit, even with relatively small data sets. The general lack of pre-packaged options for model fitting makes it difficult to compare new methodology i...

Nonparametric Mixtures of Multi-Output Heteroscedastic Gaussian Processes for Volatility Modeling

In this work, we present a nonparametric Bayesian method for multivariate volatility modeling. Our approach is based on postulation of a novel mixture of multioutput heteroscedastic Gaussian processes to model the covariance matrices of multiple assets. Specifically, we use the Pitman-Yor process prior as the nonparametric prior imposed over the components of our model, which are taken as multi...
