If you know the 'shape' or pattern of the given dataset, you can use the right kernel function when training a GP model. This is where domain knowledge of a given dataset can be useful. One fun thing I love about kernels is that you can add or multiply them to form composites.

You don't know how much cheese you'd need to insert to get a specific amount of gold. The mapping is also not linear, i.e., $G$ is not directly or inversely proportional to $C$, so bigger amount of cheese doesn't necessarily mean larger portions of gold. Your goal is to figure out how to get the largest portion of gold from this machine, assuming you
