Computationally-efficient initialisation of GPs: The generalised variogram method

1 code implementation11 Oct 2022 Felipe Tobar, Elsa Cazelles, Taco de Wolff

We present a computationally-efficient strategy to initialise the hyperparameters of a Gaussian process (GP) avoiding the computation of the likelihood function.

Towards Optimally Weighted Physics-Informed Neural Networks in Ocean Modelling

1 code implementation16 Jun 2021 Taco de Wolff, Hugo Carrillo, Luis Mart{í}, Nayat Sanchez-pi

We explore the trade-offs of using data vs. physical models in PINNs for solving partial differential equations.

Gaussian process imputation of multiple financial series

no code implementations11 Feb 2020 Taco de Wolff, Alejandro Cuevas, Felipe Tobar

In Financial Signal Processing, multiple time series such as financial indicators, stock prices and exchange rates are strongly coupled due to their dependence on the latent state of the market and therefore they are required to be jointly analysed.

MOGPTK: The Multi-Output Gaussian Process Toolkit

1 code implementation9 Feb 2020 Taco de Wolff, Alejandro Cuevas, Felipe Tobar

We present MOGPTK, a Python package for multi-channel data modelling using Gaussian processes (GP).
