Laplacian kernel class.

Inherits From: MinDiffKernel

kernel_length Length (sometimes also called 'width') of the kernel. Defaults to 0.1. This parameter essentially describes how far apart points can be and still affect each other.

The choice for kernel length should be influenced by the average distance of inputs. The smaller the distance, the smaller the kernel length likely needs to be for best performance. In general, a good first guess is the standard deviation of your predictions.

**kwargs Named parameters that will be passed directly to the base class' __init__ function.

See paper for reference on how it can be used in MinDiff.
