摘要
This paper elaborates on an orthonormal version of the projection approximation and subspace tracking (PAST) algorithm for fast estimation and tracking of principal subspace or/and principal components of a vector sequence. The orthonormal PAST (OPAST) algorithm guarantees the orthonormality of the weight matrix at each iteration. Moreover, it has a linear complexity like the PAST algorithm and a global convergence property like the natural power (NP) method.
