Variance The Estimation Eigen Value of Principal Component Analysis and Nonlinear Principal Component Analysis [PDF]

open access: yesITM Web of Conferences
Nonlinear Principal Component Analysis (PRINCALS) is an extension of Principal Component Analysis (Linear), which can reduce the variables of mixed scale multivariable data (nominal, ordinal, interval, and ratio) simultaneously.

A Low-Complexity Quantum Principal Component Analysis Algorithm

open access: yesIEEE Transactions on Quantum Engineering, 2022
In this article, we propose a low-complexity quantum principal component analysis (qPCA) algorithm. Similar to the state-of-the-art qPCA, it achieves dimension reduction by extracting principal components of the data matrix, rather than all components of

Tutorial on principal component analysis, with applications in R [PDF]

open access: yes, 2021
This tutorial reviews the main steps of the principal component analysis of a multivariate data set and its subsequent dimensional reduction on the grounds of identified dominant principal components. The underlying computations are demonstrated and performed by means of a script written in the statistical software package R.

ClustVis: a web tool for visualizing clustering of multivariate data using Principal Component Analysis and heatmap

open access: yesNucleic Acids Res., 2015
The Principal Component Analysis (PCA) is a widely used method of reducing the dimensionality of high-dimensional data, often followed by visualizing two of the components on the scatterplot. Although widely used, the method is lacking an easy-to-use web

Tensor Robust Principal Component Analysis: Exact Recovery of Corrupted Low-Rank Tensors via Convex Optimization [PDF]

open access: yesComputer Vision and Pattern Recognition, 2016
This paper studies the Tensor Robust Principal Component (TRPCA) problem which extends the known Robust PCA [4] to the tensor case. Our model is based on a new tensor Singular Value Decomposition (t-SVD) [14] and its induced tensor tubal rank and tensor ...

Principal Component Analysis of Infertility Data

open access: yesJournal of Kufa for Mathematics and Computer, 2013
This paper applied PCA on infertility set of data, that was collected from Al-Nasiriya  province.  Infertility of  women that have been unable to conceive a child after one year of their marriage without birth control. Since infertility is very common

GrIP-PCA: Grassmann Iterative P-Norm Principal Component Analysis

open access: yesIEEE Open Journal of Signal Processing, 2020
Principal component analysis is one of the most commonly used methods for dimensionality reduction in signal processing. However, the most commonly used PCA formulation is based on the L2-norm, which can be highly influenced by outlier data.

Quantifying Topographic Ruggedness Using Principal Component Analysis

open access: yesAdvances in Civil Engineering, 2021
The development of geospatial technologies has opened a new era in terms of data collection techniques and analysis procedures. Digital elevation models as 3D visualization of the Earth’s surface have many mapping and spatial analysis applications.

Probabilistic Principal Component Analysis

open access: yes, 1999
Principal component analysis (PCA) is a ubiquitous technique for data analysis and processing, but one which is not based on a probability model. We demonstrate how the principal axes of a set of observed data vectors may be determined through maximum ...
