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 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
