Résumé
It is prized when data is scarce and knowing how confident the model is matters as much as the prediction itself.

What is Gaussian Processes?
Processus Gaussien anam la wu yomb te amul ay parametre ngir modele ay fonction yuy ànd ak xayma yu wóorul dara. Dafay am solo sudee ay done bariwul, te xam ni model bi wóolu boppam moo gëna am solo ni wax ji ci boppam.
Processus Gaussian dafay màndargaal séddaleb probabilite ci kaw lan?
GP dafay def distribution ci kaw fonction yépp, kon bépp ensemble point bu am àpp dafay boole Gaussian.
Beyond a point estimate, what does a Gaussian Process return under its chosen kernel and noise assumptions?
A GP supplies a predictive distribution, but its uncertainty depends on the model assumptions and kernel.
