چکیده

The recurrent least squares (RLS) learning approach is proposed for controlling the learning rate in parallel principal subspace analysis (PSA) and in a wide class of principal component analysis (PCA) associated algorithms with a quasi{parallel extraction ability. The purpose is to provide a useful tool for applications where the learning process has to be repeated in an on{line self{adaptive manner. The methods are compared with a sequential PCA method for image compression.

Using recursive least square learning method for principal and minor components analysis

In combining principal and minor components analysis, a parallel extraction method based on recursive least square algorithm is suggested to extract the principal components of the input vectors. After the extraction, the error covariance matrix obtained in the learning process is used to perform minor components analysis. The minor components found are then pruned so as to achieve a higher com...

Adaptive Learning Algorithm for Principal Component Analysis With Partial Data

In this paper a fast and ecient adaptive learning algorithm for estimation of the principal components is developed. It seems to be especially useful in applications with changing environment , where the learning process has to be repeated in on{line manner. The approach can be called the cascade recursive least square (CRLS) method, as it combines a cascade (hierarchical) neural network scheme...

Least Squares Techniques for Extracting Water Level Fluctuations in the Persian Gulf and Oman Sea

Extracting the main cyclic fluctuations from sea level changes of the Persian Gulf and Oman Sea is vital for understanding the behavior of tides and isolating non-tidal impacts such as those related to climate and changes in the ocean-sea circulations. This study compares two spectral analysis methods including: Least Squares Spectral Analysis (LSSA) and Least Squares Harmonic Estimation (LSHE)...
