Method and device for providing a sparse gaussian process model for calculation in an engine control unit

摘要

A method for determining a sparse Gaussian process model to be carried out in a solely hardware-based model calculation unit includes: providing supporting point data points, a parameter vector based thereon, and corresponding hyperparameters; determining or providing virtual supporting point data points for the sparse Gaussian process model; and determining a parameter vector Q_y* for the sparse Gaussian process model with the aid of a Cholesky decomposition of a covariant matrix K_M between the virtual supporting point data points and as a function of the supporting point data points, the parameter vector based thereon, and the corresponding hyperparameters, which define the sparse Gaussian process model.
