Gaussian process regression tutorial
*************************************
We will see in this tutorial the basics for building a 1 dimensional and a 2 dimensional Gaussian process model, also known as a kriging model.

GP regression model before optimization of the parameters. The shaded region corresponds to 95% confidence intervals (ie +/- 2 standard deviation).
The default values of the kernel parameters may not be relevant for the current data (for example, the confidence intervals seems too wide on the previous figure). A common approach is find the values of the parameters that maximize the likelihood of the data. There are two steps for doing that with GPy:

A common approach is to find the values of the parameters that maximize the likelihood of the data. There are two steps for doing that with GPy:
* Constrain the parameters of the kernel to ensure the kernel will always be a valid covariance structure (For example, we don\'t want some variances to be negative!).
* Run the optimization
