Witryna2. Kernel methods like SVM are based on the notion of distance. To use such methods all input dimensions should have comparable ranges. For instance, if dimension 1 has a range of millions, while dimension 2 has a range of 1, the model will be completely based on dimension 1. Scaling prevents these issues. – Marc Claesen.
