Dimensional reduction by conformal bootstrap [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2019
Abstract Dimensional reductions in the branched polymer model and the random field Ising model (RFIM) are discussed by a conformal bootstrap method. Small minors are applied for the evaluations of the scale dimensions of these two models and the results are compared to the $D'=D-2$D Yang–Lee edge singularity and to the pure $D'=D-2$D ...

Exploring the Influence of Dimensionality Reduction on Anomaly Detection Performance in Multivariate Time Series [PDF]

open access: yesIEEE Access
This paper presents an extensive empirical study on the integration of dimensionality reduction techniques with advanced unsupervised time series anomaly detection models, focusing on the MUTANT and Anomaly-Transformer models.

Supersymmetry breaking by dimensional reduction over coset spaces [PDF]

open access: greenPhys.Lett.B504:122-130,2001, 2001
We study the dimensional reduction of a ten-dimensional supersymmetric E_8 gauge theory over six-dimensional coset spaces. We find that the coset space dimensional reduction over a symmetric coset space leaves the four dimensional gauge theory without any track of the original supersymmetry.

Dimensional reduction in the sky [PDF]

open access: yesPhysical Review D, 2013
We explore the cosmological implications of a mechanism found in several approaches to quantum-gravity, whereby the spectral dimension of spacetime runs from the standard value of 4 in the infrared (IR) to a smaller value in the ultraviolet (UV). Specifically, we invoke the picture where the phenomenon is associated with modified dispersion relations ...

Supervised dimensionality reduction for big data

open access: yesNature Communications, 2021
Biomedical measurements usually generate high-dimensional data where individual samples are classified in several categories. Vogelstein et al. propose a supervised dimensionality reduction method which estimates the low-dimensional data projection for ...

Haisu: Hierarchically supervised nonlinear dimensionality reduction.

open access: yesPLoS Computational Biology, 2022
We propose a novel strategy for incorporating hierarchical supervised label information into nonlinear dimensionality reduction techniques. Specifically, we extend t-SNE, UMAP, and PHATE to include known or predicted class labels and demonstrate the ...

2D Dimensionality Reduction Methods without Loss [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2019
In this paper, several two-dimensional extensions of principal component analysis (PCA) and linear discriminant analysis (LDA) techniques has been applied in a lossless dimensionality reduction framework, for face recognition application.

Dimensionality reduction methods [PDF]

open access: yesAdvances in Methodology and Statistics, 2005
In case one or more sets of variables are available, the use of dimensional reduction methods could be necessary. In this contest, after a review on the link between the Shrinkage Regression Methods and Dimensional Reduction Methods, authors provide a different multivariate extension of the Garthwaite's PLS approach (1994) where a simple linear ...
