Blind PARAFAC Signal Detection for Polarization Sensitive Array [PDF]
This paper links the polarization-sensitive-array signal detection problem to the parallel factor (PARAFAC) model, which is an analysis tool rooted in psychometrics and chemometrics.

Application of Parallel Factor Analysis (PARAFAC) to Electrophysiological Data [PDF]
The identification of important features in multi-electrode recordings requires the decomposition of data in order to disclose relevant features and to offer a clear graphical representation. This can be a demanding task.

Tracking seasonal changes of natural organic matter in a water treatment plant in Bangkok using EEM-PARAFAC approach [PDF]
This study aims to evaluate spatial and seasonal changes in natural organic matter (NOM) in Bangkhen Water Treatment Plant, Thailand. Water samples were analyzed for UV absorbance at 254 nm (UV254), dissolved organic carbon (DOC), and fluorescence ...

Multi-Sensor Fusion by CWT-PARAFAC-IPSO-SVM for Intelligent Mechanical Fault Diagnosis
A new method of multi-sensor signal analysis for fault diagnosis of centrifugal pump based on parallel factor analysis (PARAFAC) and support vector machine (SVM) is proposed. The single-channel vibration signal is analyzed by Continuous Wavelet Transform

Overview of constrained PARAFAC models [PDF]
In this paper, we present an overview of constrained PARAFAC models where the constraints model linear dependencies among columns of the factor matrices of the tensor decomposition, or alternatively, the pattern of interactions between different modes of the tensor which are captured by the equivalent core tensor.

Factor Uniqueness of the Structural Parafac Model [PDF]
Factor analysis is a well-known method for describing the covariance structure among a set of manifest variables through a limited number of unobserved factors. When the observed variables are collected at various occasions on the same statistical units, the data have a three-way structure and standard factor analysis may fail.

Dissolved organic matter (DOM) in the land–ocean interface plays a critical role in the global carbon cycle, yet its dynamic is not well understood. Dissolved organic carbon (DOC) in the northern Beibu Gulf was measured seasonally from April 2020 to ...
