}

Kernel choice for the Rvm regressor.

Variants

Linear

Linear kernel k(a, b) = aᵀb.

Rbf

Gaussian RBF kernel k(a, b) = exp(−‖a − b‖² / (2 ℓ²)) with length-scale ℓ.

Fields

length_scale: f64

Length-scale ℓ > 0.

Polynomial

Inhomogeneous polynomial kernel k(a, b) = (aᵀb + c)^d.

Fields

coef0: f64

Additive constant c ≥ 0.

degree: u32

Integer degree d ≥ 1.
