摘要
研究了L∞模的拟凸性质,利用极大熵方法得到极小化L∞模的Q算法.这是一种具有显式搜索方向的变尺度算法,在非线性参数估计中取得较好效果.
The quasi -convex properties of Loo -norm has been studied in this paper. Q-algrithm of minimum Loc, -norm has been made with maximum Entropy method. This is ametric method with the open formula of searching direction, suits for the nonlinear parame-ter est1mat1on.
