Notebook Input Output Logs Run 144.9 s history Version 3 of 3 License WebThe SVM uses what is called a “Kernel Trick” where the data is transformed and an optimal boundary is found for the possible outputs. The Need for Kernel Method and its Working Before we get into the working of the Kernel Methods, it is more important to understand support vector machines or the SVMs because kernels are implemented in SVM models.
