The paper proposes a ridge regression scheme to address parameter confounding in phenomenological models, such as those used for state‑of‑health prediction in lithium‑ion batteries. An automated, information‑theoretic method optimises the ridge hyper‑parameter at each iteration, converging rapidly via fixed‑point iteration. The resulting regularised iterative generalised least squares framework can fit heteroscedastic and serially correlated data, with simulations confirming its effectiveness.

The paper introduces a pooling‑ridge estimation method for functional linear regression that handles data observed at discrete times, ranging from sparse to dense designs. By combining pooling strategies with RKHS‑based techniques, the authors achieve minimax‑optimal prediction risk for both scalar‑on‑function and function‑on‑function models. The study identifies distinct phase transitions in convergence behavior, with up to three transitions for function‑on‑function regression, and validates the approach through simulations and real data examples.
