Application of Principal Component Analysis for Steel Material Components

open access: yesKurdistan Journal of Applied Research, 2022
In this research, we made use of the principal component analysis (PCA) technique, which is a multivariate statistical method that transforms a fixed number of correlated variables into a fixed number of orthogonal, uncorrelated axes known as principal ...

Moving objects classification via category-wise two-dimensional principal component analysis [PDF]

open access: yesApplied Computing and Informatics, 2022
Classifying moving objects in video sequences has been extensively studied, yet it is still an ongoing problem. In this paper, we propose to solve moving objects classification problem via an extended version of two-dimensional principal component ...

Sparse logistic principal components analysis for binary data [PDF]

open access: yes, 2010
We develop a new principal components analysis (PCA) type dimension reduction method for binary data. Different from the standard PCA which is defined on the observed data, the proposed PCA is defined on the logit transform of the success probabilities ...
