这个程序可以对KSVD进行综合测试。首先,会产生一个随机的正交字典,会产生一个KSVD算法输入,这个输入是一个数据信号集合,每个元素都是三维元素的线性组合。-In this file a synthetic test of the K-SVD algorithm is performed. First,
a random dictionary with normalized columns is being generated, and then
a set of data signal

字典学习。比如一个向量,是k维的,我现在有一个k*n的字典,其中n>>k,所谓的字典学习,就是在这包含n个向量的字典当中寻找一个线性表示可以表示出当前这个k维的向量。之所以称为“稀疏表示”,因为一般n大于k,比如n=512,k=64。这时候你的字典一定是一个Redundant(冗余的,过剩的)的。因此你的表示里面一定有很多系数为0,因而被称作稀疏表示。
信号稀疏表示的目的就是在给定的超完备字典中用尽可能少的原子来表示信号,可以获得信号更为简洁的表示方式,从而使我们更容易地获取信号中
