Definitions for "Preconditioning"
(n.) a technique for improving the convergence of iterative matrix inversion algorithms such as the conjugate gradient method, by transforming the matrix of equation coefficients so that the eigenvalues are redistributed.
The process of choosing new control variables which are exactly, or approximately uncorrelated, and form a unit Hessian matrix. In a perfectly preconditioned system of equations, contours of constant cost function are circles in the new control variable space and the preconditioning number is unity.
Preparation of feeder calves for marketing and shipment, may include vaccinations, castration, and training calves to eat and drink in pens.
drilling of holes ahead of the face to be blasted and detonating these with a light charge. To mitigate against mining-induced seismicity.
