Gaussian kernel coefficients depend on the value of σ. At the edge of the mask, coefficients must be close to 0. The kernel is rotationally symme tric with no directional bias. Gaussian kernel is separable which allows fast computation 25 Gaussian kernel is separable, which allows fast computation. Gaussian filters might not preserve image

One-dimensional Gaussian kernel.
RBF (Gaussian) kernel Based on the above results we could say that the dataset is non- linear and Support Vector Regression (SVR)performs better than traditional Regression however there is a caveat, it will perform well with non-linear kernels in SVR. You can create a Gaussian kernel from scratch as noted in MATLAB documentation of fspecial .

The selection of variance would determine the bias-variance trade-offs. Higher value of variance would result in High bias, low variance classifier and, lower value of variance would result in low bias/high variance classifier. A Gaussian kernel is a kernel with the shape of a Gaussian (normal distribution) curve. Here is a standard Gaussian, with a mean of 0 and a \(\sigma\) (=population standard deviation) of 1.
