Struct SEardKernel 

pub struct SEardKernel { /* private fields */ }

Squared Exponential function (SEard) kernel The distance metric here is L2 (Euclidean).

    k(a, b) = exp(-0.5 * (a - b)' * M * (a - b))

Parameters

• M - Length scale for each dimension.

Reports if the given kernel function is stationary.

fn diag<R, C, S>(&self, x: &Matrix<f64, R, C, S>) -> DVector<f64>

where R: Dim, C: Dim, S: Storage<f64, R, C>,

Returns the diagonal of the kernel(x, x)

fn parameters(&self) -> DVector<f64>

Return the corresponding parameter vector The parameters here are in a log-scale

fn reparameterize(&self, params: &[f64]) -> Result<Self, KernelError>

Create a new kernel of the given type from the provided parameters. The parameters here are in a log-scale

fn covariance_with_gradient<R, C, S>( &self, x: &Matrix<f64, R, C, S>, ) -> Result<(DMatrix<f64>, CovGrad), CovGradError>

where R: Dim, C: Dim, S: Storage<f64, R, C>,

type Output = ProductKernel<SEardKernel, B>

The resulting type after applying the * operator.

fn mul(self, rhs: B) -> Self::Output

impl PartialEq for SEardKernel

fn eq(&self, other: &SEardKernel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SEardKernel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
