Clustering of eclipsing binary light curves through functional principal component analysis

نویسندگان

چکیده

In this paper, we revisit the problem of clustering 1318 new variable stars found in Milky way. Our recent work distinguishes these based on their light curves which are univariate series brightness from observed at discrete time points. This proposes a approach to look as continuous over by transforming them into functional data. Then, principal component analysis is performed using curves. Clustering significant components reveals two distinct groups eclipsing binaries with consistency and superiority compared our previous results. method established powerful curve-based classifier, where implementation simple algorithm effective enough uncover true clusters merely first few relevant components. Simultaneously discard noise data study involving higher order Thus suggested very useful for big curve sets also verified simulation study.

Binary Principal Component Analysis

Efficient and compact representation of images is a fundamental problem in computer vision. Principal Component Analysis (PCA) has been widely used for image representation and has been successfully applied to many computer vision algorithms. In this paper, we propose a method that uses Haar-like binary box functions to span a subspace which approximates the PCA subspace. The proposed method ca...

Principal Component Analysis of RR Lyrae light curves

In this paper, we analyze the structure of RRab star light curves using Principal Component Analysis. We find this is a very efficient way to describe many aspects of RRab light curve structure: in many cases, a Principal Component fit with 9 parameters can describe a RRab light curve including bumps whereas a 17 parameter Fourier fit is needed. As a consequence we show show statistically why t...

Functional principal component analysis of H-reflex recruitment curves.

The primary purpose of this study was to use functional principal component analysis (FPCA) to analyze Hoffman-reflex (H-reflex) recruitment curves. Smoothed and interpolated recruitment curves from 38 participants were used for analysis. Standard methods were used to calculate three discrete variables (i.e., H(max)/M(max) ratio, H(th), H(slp)). FPCA was then used to extract principal component...

Multilevel Functional Principal Component Analysis.

The Sleep Heart Health Study (SHHS) is a comprehensive landmark study of sleep and its impacts on health outcomes. A primary metric of the SHHS is the in-home polysomnogram, which includes two electroencephalographic (EEG) channels for each subject, at two visits. The volume and importance of this data presents enormous challenges for analysis. To address these challenges, we introduce multilev...

Local functional principal component analysis

Covariance operators of random functions are crucial tools to study the way random elements concentrate over their support. The principal component analysis of a random function X is well-known from a theoretical viewpoint and extensively used in practical situations. In this work we focus on local covariance operators. They provide some pieces of information about the distribution of X around ...
