What is the significance of Gamma and Regularization in SVM?

SpletThe kernel parameter γ is used to control the locality of the kernel function. It varies between 0 and ∞ (in these limits the kernel matrix becomes the one matrix and unit matrix, respectively). Good values are somewhere in between. It is crucial to optimize these parameters to obtain a good model.
