10/14/13 1 More on kernel functions 1 Kernels Definition: A function k(x, z) that can be expressed as a dot product in some feature space is called a kernel. In other words, k(x, z) is a kernel if there exists Aug 25, 2019 · Kernel Functions. The idea of kernel functions is to take the inner products between two feature vectors, and evaluate inner products is not computationally costly. We can then exploit only the result of the inner products in our algorithms. For example, if we want to have the ϕ(x) as follows, In set theory, the kernel of a function f may be taken to be either the equivalence relation on the function's domain that roughly expresses the idea of "equivalent as far as the function f can tell", or; the corresponding partition of the domain. In nonparametric statistics, a kernel is a weighting function used in non-parametric estimation techniques. Kernels are used in kernel density estimation to estimate random variables' density functions, or in kernel regression to estimate the conditional expectation of a random variable.

A kernel is a similarity function. It is a function that you, as the domain expert, provide to a machine learning algorithm. It takes two inputs and spits out how similar they are. Suppose your task is to learn to classify images. You have (image, label) pairs as training data. The kernel is effectively a similarity measure, so choosing a kernel according to prior knowledge of invariances as suggested by Robin (+1) is a good idea. In the absence of expert knowledge, the Radial Basis Function kernel makes a good default kernel (once you have established it is a problem requiring a non-linear model).
