Bayesian interpretation of kernel regularization

term_id: bayesian_interpretation_of_kernel_regularization

Category: training_techniques

Definition

This concept establishes that minimizing a regularized risk functional with a specific kernel is equivalent to finding the maximum a posteriori (MAP) estimate in a Bayesian framework. Specifically, it interprets the regularization term as a log-prior over functions, often corresponding to a Gaussian Process prior. This connection allows practitioners to apply Bayesian uncertainty quantification techniques to deterministic kernel methods, providing probabilistic predictions and insights into model confidence.
