Unbiased Estimation Formula of Unit Weight Mean Square Error in Regularization Solution

    Abstract
  • Regularization method is an effective method in solving ill-posed equation.In this paper the unbiased estimation formula of unit weight mean square error in the regularization solution is derived and the formula is verified with numerical test of 1 000 sample data by use of the typical ill-posed equation,i.e.the Fredholm integration equation of the first kind.
