The functions from this prior are ridiculously smooth for many purposes, and other choices may be better. (In high-dimensions you can’t really see any detail of a function, and the smoothness of the Gaussian kernel probably matters less.) Kernels usually have parameters. With Gaussian kernel, correntropy is a localized similarity measure between two random variables: when two points are close, the correntropy induced metric (CIM) behaves like an L2 norm; outside of the L2 zone CIM behaves like an L1 norm; as two points are further apart, the metric approaches L0 norm [137]. This implies that the kernel should have an odd height (resp. width) to ensure that there actually is a central element. To compute the actual kernel elements you may scale the gaussian bell to the kernel grid (choose an arbitrary e.g.

Creating a discrete Gaussian kernel with Python Discrete Gaussian kernels are often used for convolution in signal processing, or, in my case, weighting. The length scale of the kernel. See [1], Chapter 4, Section 4.2, for details regarding the different (appr. Gaussian Kernel; In the example with TensorFlow, we will use the Random Fourier.
