網頁Unconstrained and constrained optimization criteria for extracting multiple true canonical variates and canonical correlations are proposed. These include a weighted information criterion (WINC-CCA) and a shifted information criterion (SINC-CCA) for searching the optimal solutions. The gradient flows of the proposed CCA functions are analyzed and … 網頁The best methods seems to be the modified Benders decomposition method and the dual ascent method with branch and bound. These methods are capable of solving quite large problems (up to almost 3,000,000 variables) optimally. ifor williams email address https://posesif.com
