We give a simple technique for verifying the Restricted Isometry Property (as introduced by Cand`es and Tao) for random matrices that underlies Compressed Sensing. Our approach has two main ingredients: (i) concentration inequalities for random inner products that have recently provided algorithmically simple proofs of the Johnson-Lindenstrauss lemma, (ii) covering numbers for finite dimensional balls in Euclidean space. This leads to an elementary proof of the Restricted Isometry Property and brings out connections between Compressed Sensing and the Johnson-Lindenstrauss lemma. As a result, we obtain simple and direct proofs of Kashin’s theorems on widths of finite balls in Euclidean space (and their improvements due to Gluskin) and proofs of the existence of optimal Compressed Sensing measurement matrices. In the process we also prove that these measurements have a certain universality with respect to the sparsity inducing basis.

跨域请求时,页面报错“Access-Control-Allow-Origin”, 因为浏览器只允许请求当前域的资源,而对其他域的资源表示不信任。需要配置cors全称是"跨域资源共享"(Cross-origin resource sharing)。以tomcat为例子在 一. 在tomcat的lib目录下添加jar包cors-filter-1.5.0.1.jar,java-property-utils-1.9.jar 二. tomcat路径下conf/web.xml文件中添加以下内容,可以在原文件中找到标签酌情添加。不要加到开头或者结尾。 CORS com.thetransactioncompany.cors.CORSFilter cors.allowOrigin * cors.supportedMethods GET, POST, HEAD, PUT, DELETE cors.supportedHeaders Accept, Origin, X-Requested-With, Content-Type, Last-Modified cors.exposedHeaders Set-Cookie cors.supportsCredentials true CORS /* 在三台机器上已测试全部有效。
