Calibrated Derivative-Process Sensitivity for Gaussian-Process Variable Selection

arXiv:2609.33549v1 Announce Type: new Abstract: Automatic relevance determination (ARD), the default tool for variable selection in Gaussian-process (GP) regression, ranks inputs by inverse lengthscales -- which measure how fast a function varies, not how much an input contributes to prediction --…
