A Robust Pca Modeling Method for Process Monitoring
A robust method for dealing with the gross errors in the data collected for PCA model is proposed. This method, using M-estimator based on the generalized t distribution, adaptively transforms the data in the score space in order to eliminate the effects of the outliers in the original data. The robust estimation of the covariance or correlation matrix is obtained by the proposed approach so th...
متن کاملBiological Nitrogen Removal Process Monitoring Based on Fuzzy Robust PCA
In this study the Fuzzy Robust Principal Component Analysis (FRPCA) method is used to monitor a biological nitrogen removal process, performances of this method are then compared with classical principal component analysis. The obtained results demonstrate the performances superiority of this robust extension compared with the conventional one. In this method fuzzy variant of PCA uses fuzzy mem...
متن کاملA Statistical Method for Sequential Images – Based Process Monitoring
Today, with the growth of technology, monitoring processes by the use of video and satellite sensors have been more expanded, due to their rich and valuable information. Recently, some researchers have used sequential images for image defect detection because a single image is not sufficient for process monitoring. In this paper, by adding the time dimension to the image-based process monitorin...
متن کاملTemperature Robust PCA Based Stress Monitoring Approach
In this paper, a guided wave temperature robust PCA-based stress monitoring methodology is proposed. It is based on the analysis of the longitudinal guided wave propagating along the path under stress. Slight changes in the wave are detected by means of PCA via statistical T 2 and Q indices. Experimental and numerical simulations of the guided wave propagating in material under different temper...
متن کاملA New Pca–based Robust Color Image Watermarking Method
Although, the possibility of electronic storage and transmission has been bene cial for extending the intellectual communication, the easiness of copying and transmitting the data in the internet has increased the piracy and illegal use of owned artworks. As a result, digital data watermarking, has been under thorough investigation in recent years. The main aim of data hiding is to add some tra...
