Drift¶
ferreus_rbf.interpolant_config.Drift
¶
Bases: Enum
The name of the polynomial order to add to the RBF system.
The drift affects the interpolant away from data locations.
To ensure a unique solution to the RBF system of equations, some kernels have a minimum required polynomial that must be added, as shown below.
| Kernel | Minimum drift | Default drift |
|---|---|---|
| Linear | Constant | Constant |
| ThinPlateSpline | Linear | Linear |
| Cubic | Linear | Linear |
| Spheroidal | None | None |
