where p denotes the observation vector, U is the matrix composed of eigenbasis vectors, q is the coefficients of eigenbasis vectors and e indicates the pixels in p that are corrupted or occluded. 估计目标可以由PCA基向量建模,另外的琐碎模版在论文16中使用 , p表示观测向量,U是正交基向量构成的矩阵...
mean vector of \(Y_{t}\) is independent of the time t, and for any times t and s, the covariance matrix \(Cov(Y_{t},Y_{s})\) depends only on \(t-s\).In addition we assume that the process has zero mean (since any systematic trend can be always removed from the data)....

To generate computationally efficient computer program code for carrying out computer computations on matrix organized input data, a program first is written in a relatively high-level language which
