In the Using ridge regression to overcome linear regression's shortfalls recipe, we discussed the connections between the constraints imposed by ridge regression from an optimization standpoint. We also discussed the Bayesian interpretation of priors on the coefficients, which attract the mass of the d...

Linear regression with regularization Large λ High bias (underfit) Small λ High variance (overfit) So how do we choose a good value of λ? H(θ): algorithm; hypothesis J(θ): cost function; optimization objective Jtrain(θ), Jcv(θ), Jtest(θ): optimization objectives without...

(Mitchell,1997, p. 23). This is called the hypothesis space, and an example would be that of a linear regression algorithm that has all linear functions in this set. This also relates to the No-free-Lunch theorem: As models can be thought of as simplifications of the observations/data,...

This appears to be problematic, especially for kernel ridge regression (KRR) and the other variants on linear regression, which treat each element separately and for which it is usually assumed that each element has the same meaning in every sample. Bag of bonds The bag of bonds featurization...
