Expand description

Compute the Gram matrix between two datasets

K[i,j] = k(x_i, y_j)

§Arguments

  • x - First input data, shape (n_x, n_features)
  • y - Second input data, shape (n_y, n_features)
  • kernel - The kernel function type

§Returns

  • Result<Array2<f64>> - The cross-kernel matrix, shape (n_x, n_y)
