Support vector machine kernel function
WebApr 30, 2024 · A Kernel function can be written mathematically as follows: equation 6 Here x and y are input vectors, ϕ is a transformation function and < , > denotes dot product operation. In the case of dot product function, ϕ just maps the input vector to itself. Kernel functions essentially take the dot product of transformed input vectors. WebAug 7, 2024 · Kernel function is a function of form– ... Radial kernel support vector machine is a good approach when the data is not linearly separable. The idea behind generating non-linear decision boundaries is that we need to do some nonlinear transformations on the features X\(_i\) which transforms them into a higher dimensional space. ...
