WebIn calculus, Newton's method is an iterative method for finding the roots of a differentiable function F, which are solutions to the equation F (x) = 0. As such, Newton's method can be applied to the derivative f ′ of a twice-differentiable function f to find the roots of the derivative (solutions to f ′ (x) = 0 ), also known as the ... WebThe Bregman iteration is a well established method for the solution of ℓ 1-regularized optimization problems. It has been successfully applied not only in compressed sensing but also in different fields, such as image analysis [25,26], matrix rank minimization , and finance [28,29].
