PDF-CONJUGATE GRADIENT METHOD MATH SPRING Abstract

This short note is on the derivation and convergence of a popular algorithm for minimization of quadratic functionals or solving linear systems known as the method of Conjugate Gradients CG To the best of the knowledge of the author of this short n.

Gradient descent is an iterative method that is given an initial point and follows the negative of the gradient in order to move the point toward a critical point which is hopefully the desired local minimum Again we are concerned with only local op 5 ME 360 35 ME 370 ME 320 ME 350 ME 390 HumSoc HumSoc ME 371 Free Elec Tech Elec MechSE Elec Statistics Tech Elec 46 Science Elec MechSE Elec Free Elec Eng 100 1415 hrs 1415 hrs 16 hrs 16 hrs 175 hrs 165 hrs 18 hrs 15 hrs ME 199 ME 199 ME 199 Freshma By the way the gradient of isnt always denoted sometimes its denoted grad As you know the gradient of a scalar eld is f x f x f x We can abstract this by leaving out the to get an operator x x x which when applied to yields This is called t to.
