cuckoo_search
- 布谷鸟搜索(Cuckoo Search,缩写 CS),也叫杜鹃搜索,是由剑桥大学杨新社(音译自:Xin-She Yang)教授和S.戴布(S.Deb)于2009年提出的一种新兴启发算法[1]。 CS算法是通过模拟某些种属布谷鸟的寄生育雏(Brood Parasitism) [2],来有效地求解最优化问题的算法[3]。同时,CS也采用相关的Levy飞行搜索机制。研究表明,布谷鸟搜索比其他群体优化算法更有效-Cuckoo search (Cuckoo Search, acronym CS)
cuckoo

CS
- 因为自然界的数据都存在局部低维结构、周期性、对称性等,因此,传统的固定采样率的采样方法必然存在信息冗余。由于信息冗余的存在,我们就知道有数据压缩那么一门学科。既然这样,为什么要把冗余的数据也采进来,再进行压缩呢,能不能不把冗余的数据采集进来? 压缩感知的思路就是:在采集的过程中就对数据进行了压缩,而且这种压缩能保证不失真(低失真)的恢复原始数据,这与传统的先2倍频率采集信号→存储→再压缩的方式不同,可以降低采集信号的存储空间和计算量。 本程序是对于压缩感知模型的数学描述(Mathematics
