Struct argmin::solver::landweber::Landweber [−][src]
pub struct Landweber<F> { /* fields omitted */ }
The Landweber iteration is a solver for ill-posed linear inverse problems.
In iteration k
, the new parameter vector x_{k+1}
is calculated from the previous parameter
vector x_k
and the gradient at x_k
according to the following update rule:
x_{k+1} = x_k - omega * \nabla f(x_k)
