Ridge regression with adaptive additive rectangles and other piecewise functional templates
Edoardo Belli, Simone Vantini
We propose an -based penalization algorithm for functional linear regression models, where the coefficient function is shrunk towards a data-driven shape template , which…

Smoothly Adaptively Centered Ridge Estimator
Edoardo Belli
With a focus on linear models with smooth functional covariates, we propose a penalization framework (SACR) based on the nonzero centered ridge, where the center of the penalty is…
