spleaf.Spleaf.grad_param

Spleaf.grad_param(*args, **kwargs)

Gradient of a function with respect to the initial parameters (A, U, V, phi, F), after a call to cholesky_back().

Returns:

grad_A(n,) ndarray

Gradient of the function with respect to A.

grad_U(n, r) ndarray

Gradient of the function with respect to U.

grad_V(n, r) ndarray

Gradient of the function with respect to V.

grad_phi(n-1, r) ndarray

Gradient of the function with respect to phi.

grad_Fndarray

Gradient of the function with respect to F.
