function[hard_thresh]=hardthresholding(b,lambda)sel=(abs(b)>sqrt(lambda));hard_thresh=b.*sel;end 一定要注意:这种写法是针对最开始的优化问题: 但我个人感觉更应该写成这种通用形式: 代码语言:javascript 复制 function[x]=hard(b,T)sel=(abs(b)>T);x=b.*sel;end 如此之后,若要解决优化问题 只需...
function[ x ] = hard( b,T ) sel = (abs(b)>T); x = b.*sel; end 如此之后,若要解决优化问题 只需调用hard(B, sqrt(λ))即可;若要解决优化问题 只需调用hard(B, sqrt(2*λ))即可。 5、硬阈值(HardThresholding)测试代码 硬阈值(Hard Thresholding)要解决的优化问题目标函数是非凸的,不太常见...

Hard Thresholding Pursuit (HTP) is an iterative greedy selection procedure for finding sparse solutions of underdetermined linear systems. This method has been shown to have strong theoretical guarantee and impressive numerical performance. In this paper, we generalize HTP from compressive sensing to a ...
