New Conditional KRR Method Enhances Kernel Regression with Unpenalized Features

By PulseAugur Editorial · [2 sources] ·

A new paper introduces Conditional Kernel Ridge Regression (Conditional KRR), a method that enhances standard KRR by incorporating unpenalized features. This approach is beneficial when a specific function class, denoted as \(\\mathcal{F}\\) , significantly influences the target variable. The research demonstrates that Conditional KRR can be analyzed by reducing it to a standard KRR problem with a modified 'residual kernel'. Theoretical results show an \(\mathcal{O}(1/\sqrt{N})\) bound on the expected test risk, and experiments confirm that Conditional KRR outperforms standard KRR when the \(\mathcal{F}\)-component is more pronounced.

    Conditionally positive definite (CPD) kernels are defined with respect to a function class $\mathcal{F}$. It is well known that such a kernel $K$ is associated with its native space (defined analogously to an RKHS), which in turn gives rise to a learning method -- called conditio…
