Function kernel_target_alignment 

Source 
pub fn kernel_target_alignment(
    k: &KernelMatrix,
    target: &KernelMatrix,
) -> Result<AlignmentResult, AlignmentError>
Expand description

Compute the Kernel Target Alignment (KTA) between kernel k and target kernel target.

KTA(K, T) = <K, T>_F / (||K||_F * ||T||_F)

The score lies in [-1, 1]; values near 1 indicate the kernel faithfully encodes the label structure.
