Function kernel_alignment 

Source 
pub fn kernel_alignment(k1: &Array2<f64>, k2: &Array2<f64>) -> Result<f64>
Expand description

Kernel alignment between two kernel matrices

The alignment A(K1, K2) = <K1, K2>_F / (||K1||_F * ||K2||_F) where <.,.>_F is the Frobenius inner product.

This measures how similar two kernel matrices are.

§Arguments

  • k1 - First kernel matrix
  • k2 - Second kernel matrix

§Returns

  • Result<f64> - The alignment score in [0, 1]
