Application of kernel principal component analysis for optical vector atomic magnetometry [PDF]

open access: yesMachine Learning: Science and Technology, 2023
Vector atomic magnetometers that incorporate electromagnetically induced transparency (EIT) allow for precision measurements of magnetic fields that are sensitive to the directionality of the observed field by virtue of fundamental physics.

Towards Multiple Kernel Principal Component Analysis for Integrative Analysis of Tumor Samples [PDF]

open access: yesJournal of Integrative Bioinformatics, 2017
Personalized treatment of patients based on tissue-specific cancer subtypes has strongly increased the efficacy of the chosen therapies. Even though the amount of data measured for cancer patients has increased over the last years, most cancer subtypes ...

Two-Phase Incremental Kernel PCA for Learning Massive or Online Datasets [PDF]

open access: yesComplexity, 2019
As a powerful nonlinear feature extractor, kernel principal component analysis (KPCA) has been widely adopted in many machine learning applications. However, KPCA is usually performed in a batch mode, leading to some potential problems when handling ...

Nonlinear chemical processes fault detection based on adaptive kernel principal component analysis

open access: yesSystems Science & Control Engineering, 2020
When kernel Principal Component Analysis (KPCA) is applied to fault detection, kernel Principal Components (KPCs) are divided into two spaces according to the size of variance for fault detection, respectively.

Kernel Principal Component Analysis of Coil Compression in Parallel Imaging. [PDF]

open access: yesComput Math Methods Med, 2018
A phased array with many coil elements has been widely used in parallel MRI for imaging acceleration. On the other hand, it results in increased memory usage and large computational costs for reconstructing the missing data from such a large number of channels.

Visualization of Iris Data Using Principal Component Analysis and Kernel Principal Component Analysis

open access: yesJurnal Ilmu Dasar, 2010
Principal component analysis (PCA) is a method used to reduce dimentionality of the dataset. However, the use of PCA failed to carry out the problem of non-linear and non-separable data.

Exactly Robust Kernel Principal Component Analysis [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2020
Robust principal component analysis (RPCA) can recover low-rank matrices when they are corrupted by sparse noises. In practice, many matrices are, however, of high-rank and hence cannot be recovered by RPCA. We propose a novel method called robust kernel principal component analysis (RKPCA) to decompose a partially corrupted matrix as a sparse matrix ...
