funGp-package: Gaussian Process Models for Scalar and Functional Inputs

Description

Construction and smart selection of Gaussian process models with emphasis on treatment of functional inputs.

Base functionalities

• Main methods fgpm: creation of funGp regression models predict: output estimation at new input points based on a funGp model simulate: random sampling from a funGp Gaussian process model update: modification of data and hyperparameters of a funGp model

• Plotters plotLOO: validation plot for a funGp model plotPreds: plot of predictions based on a funGp model plotSims: plot of simulations based on a funGp model

Model selection

• Main methods fgpm_factory: structural parameter optimization

• Plotters pre-optimization decay: regularized initial pheromones decay2probs: normalized initial pheromones

• Plotters post-optimization plotX: absolute and relative quality of the optimized model plotEvol: evolution of the algorithm
