Why Kernels - Practical Machine Learning Tutorial with Python p.30

Once we've determined that we can use Kernels, the next question is of course why would we bother using kernels when we can use some other function to transform our data into more dimensions. The point of using Kernels is to be able to perform a calculation (inner product in this case) in another dimension without actually needing to work in that dimension. https://pythonprogramming.net   / sentdex     / pythonprogramming.net   https://plus.google.com/+sentdex
