PROPAGATION OF UNCERTAINTY IN BAYESIAN KERNEL MODELS — APPLICATION TO MULTIPLE-STEP AHEAD FORECASTING (2009)

Joaquin Quiñonero C, Agathe Girard, Jan Larsen, Carl Edward Rasmussen

The object of Bayesian modelling is the predictive distribution, which in a forecasting scenario enables evaluation of forecasted values and their uncertainties. In this paper we focus on reliably...

Abstract (2007)

Agathe Girard, Roderick Murray-smith

Learning with uncertain inputs is well-known to be a difficult task. In order to achieve this analytically using a Gaussian Process prior model, we expand the original process around the input mean...

Approximate methods for propagation of uncertainty with gaussian process models. Doctoral dissertation (2004)

Agathe Girard, C Agathe Girard

This thesis presents extensions of the Gaussian Process (GP) model, based on approximate methods allowing the model to deal with input uncertainty. Zero-mean GPs with Gaussian covariance function are...

Adaptive, cautious, predictive control with Gaussian process priors (2003)

Roderick Murray-Smith, Daniel Sbarbaro, Carl Edward Rasmussen, Agathe Girard

Nonparametric Gaussian Process models, a Bayesian statistics approach, are used to implement a nonlinear adaptive control law. Predictions, including propagation of the state uncertainty are made...

Prediction at an Uncertain Input for Gaussian Processes and Relevance Vector Machines - Application to Multiple-Step Ahead Time-Series Forecasting (2002)

Agathe Girard, Carl Edward Rasmussen

We consider in this report non-linear models that map an input D-dimensional column vector x into a single dimensional output f(x). The non-linear mapping f() is implemented by means of a Gaussian...

Title ASSESSING THE COMPLEXITY OF MULTI-DIMENSIONAL MIS- FIT FUNCTIONS (1999)

Old Quarry Road, Agathe Girard, Andrew Curtis, Schlumberger Cambridge, Author(s Agathe Girard, Andrew Curtis

This report compares two methods to assess the complexity of nonlinear inverse problems. Each method attempts to estimate the number of minima in the data misfit function. The first method uses...
