5. 内存受限的拟牛顿法(L-BFGS) 拟牛顿法虽然避免了牛顿法求解Hession逆矩阵的复杂运算,但是即使通过计算近似矩阵B可以替代Hession逆矩阵,但是矩阵B也会占用大量的内存空间,如果优化变量的size为n,那么矩阵B的size就是n*n,如果变量为1000000个,那么B矩阵中数字个数为1000000*1000000,因此为了避免因为内存无法存储B矩...
L-BFGS-B is a fantastic NNLS solver, and much better than Matlab's lsqnonneg. Links: The fortran lbfgsb is at http://users.eecs.northwestern.edu/~nocedal/lbfgsb.html, There are also versions 2.1 and 2.4 of the library. For v 2.1, Peter Carbonetto's mex interface works; see http:...
目前BFGS或L-BFGS已经被应用得极为普遍,诸如量子化学程序里做几何优化主要就是基于BFGS的思想。 从耗时来说,牛顿法>BFGS>L-BFGS,而从优化效率来说(达到同样精度所需步数),也是牛顿法>BFGS>L-BFGS(但差距不算特别大)。 L-BFGS-B的作者直接提供了实现L-BFGS-B算法的Fortran 77的代码,见http://users.iems.no...
