The data model of compressive sensing is y=A*x+e. y is an M-dimensional
vector of measurements, A is an M by N matrix, x is an N-dimensional vector
of signal and e the noise vector. There is only a limited number of
measurements, meaning M signal x from y by making use of the fast that x is a sparse vector.
If M>N, then one can estimate x by maximum-likelihood (equivalent to least-
squares method). However, when M

it is closely related to sparse coding, basis persuit, LASSO, which is very

呵呵,Tao等人的工作之后,所有相关的community,都开始用不同的响应速度来靠这棵
大树,从Stat.,Signal Processing, Coding theory,Information theory,Image
Processing, Computer Vision,Machine Learning,Communication。。。
这个确实是好的工作,但后面很多靠着的都是有牵强附会的嫌疑~~
