WebSpline features make it possible for the linear model to successfully leverage the periodic time-related features and reduce the error from ~14% to ~10% of the maximum demand, which is similar to what we observed with the one-hot encoded features. Qualitative analysis of the impact of features on linear model predictions ¶ Web1 Apr 2024 · The TCB-spline-based parameterization for Ω is to find a mapping G such that G: Ω ˆ Ω, G (t) ≔ ∑ I ∈ I k R I (t) p I, t (u, v) ∈ Ω ˆ, where Ω ˆ is called a parametric domain, and p I ∈ R 2 is a control point associated with the rational TCB-spline (RTCB-spline) basis function R I defined in Ω ˆ.
