A TEMPORAL EXTENSION TO TRADITIONAL EMPIRICAL ORTHOGONAL FUNCTION ANALYSIS [PDF]

open access: yesAnalysis of Multi-Temporal Remote Sensing Images, 2002
This paper describes the application of temporal maximum autocorrelation factor analysis to global monthly mean values of 1996-1997 sea surface temperature (SST) and sea surface height (SSH) data. This type of analysis can be considered as an extension of traditional empirical orthogonal function (EOF) analysis, which provides a non-temporal analysis ...

A BIVARIATE EXTENSION TO TRADITIONAL EMPIRICAL ORTHOGONAL FUNCTION ANALYSIS [PDF]

open access: yesAnalysis of Multi-Temporal Remote Sensing Images, 2002
This paper describes the application of canonical correlations analysis to the joint analysis of global monthly mean values of 1996-1997 sea surface temperature (SST) and height (SSH) data. The SST data are considered as one set and the SSH data as another set of multivariate observations, both with 24 variables. This type of analysis can be considered

Displacement convexity for the generalized orthogonal ensemble. [PDF]

open access: yes, 2004
The paper considers the generalized ensemble of n by n real symmetric matrices that is invariant under the natural action of the real orthogonal group and that is given by a real potential function.

Modeling TEC Irregularities in the Arctic Ionosphere Using Empirical Orthogonal Function Method

open access: yesSpace Weather, 2023
We develop a climatological model for the Arctic ionosphere based on more than one solar cycle of data (2010–2021) of the rate of change of the total electron content index (ROTI) maps from the International GNSS Service (IGS).

Fully complex-valued radial basis function networks: orthogonal least squares regression and classification [PDF]

open access: yes, 2008
We consider a fully complex-valued radial basis function (RBF) network for regression and classification applications. For regression problems, the locally regularised orthogonal least squares (LROLS) algorithm aided with the D-optimality experimental ...

The Relationship Between the SST of the Surface Mediterranean and the Temperature/Precipitation of Middle East Using Empirical Orthogonal Function For the Period (1980-2009)

open access: yesAl-Mustansiriyah Journal of Science, 2017
The aim of this study is to identify the variations of Sea Surface Temperature (SST) of the Mediterranean Sea and the variations of air surface temperature and to total precipitation over the Middle East. In order to find the possible correlation between

Climatology and modeling of ionospheric irregularities over Greenland based on empirical orthogonal function method

open access: yesJournal of Space Weather and Space Climate, 2022
This paper addresses the long-term climatology (over two solar cycles) of total electron content (TEC) irregularities from a polar cap station (Thule) using the rate of change of the TEC index (ROTI).

A Novel Method of Ionospheric Inversion Based on Horizontal Constraint and Empirical Orthogonal Function

open access: yesRemote Sensing, 2023
Tomographic inversion of the ionosphere is a rank-deficient problem. To overcome the above problem, an algebraic reconstruction technique (ART) based on adaptive horizontal constraint and empirical orthogonal function (ARTHCEOF) is proposed.

Orthogonal least squares algorithm for training multi-output radial basis function networks [PDF]

open access: yes, 1991
A constructive learning algorithm for multioutput radial basis function networks is presented. Unlike most network learning algorithms, which require a fixed network structure, this algorithm automatically determines an adequate radial basis function ...

VARIABILITAS KLOROFIL-a PERIODE INDIAN OCEAN DIPOLE DI SELAT BALI BERDASARKAN ANALISIS EMPIRICAL ORTHOGONAL FUNCTION

open access: yesJFMR-Journal of Fisheries and Marine Research, 2021
Perairan Selat Bali secara tidak langsung dipengaruhi oleh peristiwa yang terjadi di Samudera Hindia Selatan Jawa. Variabilitas musim dan antar-tahunan dari konsentrasi klorofil-a permukaan (SSC) di Selat Bali, berhubungan erat dengan periode Indian ...
