Proximal OperatorsΒΆ
The proximal_operators
module contains functions to compute the following proximal operators:
- Proximal operator of the nuclear norm (
nucnorm
) - Proximal operator of the l1 norm (
sparse
) - Proximal operator corresponding to solving a linear system of equations (
linsys
) - Proximal operator of the l2 norm, a squared error penalty (
squared_error
) - Proximal operator for minimizing an arbitrary smooth function given an oracle that computes the function value and gradient (
lbfgs
) - Pxorimal operator for the l2 penalty of the discrete different operator, to encourage smoothness (
smooth
) - Projection onto the non-negative orthant (
nonneg
) - Projection onto the semidefinite cone (
semidefinite_cone
)
