WebbAn Algorithm for Bayesian Ridge Regression¶. This guide describes a Bayesian algorithm for regularized linear regression. The algorithm uses a hyperparameter to control regularization strength and fully integrates over the hyperparameter in the posterior distribution, applying a hyperprior selected so as to be approximately noninformative.

Webb18 aug. 2024 · Iterative imputation refers to a process where each feature is modeled as a function of the other features, e.g. a regression problem where missing values are predicted. Each feature is imputed sequentially, one after the other, allowing prior imputed values to be used as part of a model in predicting subsequent features.

In ridge regression we have some sort of prior over weights w γ ∼ N ( 0, γ 2 I) and the likelihood model y x, w, σ ∼ N ( w, x , σ 2). If we want to stop conditioning on the variances in the prior/likelihood, we can place a prior over each and marginalize these out during prediction.
