Three-way component analysis with smoothness constraints
Tucker3 Analysis and CANDECOMP=PARAFAC (CP) are closely related methods for threeway component analysis. Imposing constraints on the Tucker3 or CP solutions can be useful to improve estimation of the model parameters. In the present paper, a method is proposed for applying smoothness constraints on Tucker3 or CP solutions, which is particularly useful in analysing functional three-way data. The...
متن کاملThree-way Component Analysis: An overview and some new developments
Rennes, December 2 Three-way Component Analysis: An overview and some new developments Henk A.L. Kiers University of Groningen Three-way data are data associated with three sets of units. As an example of threeway data one may have scores of a set of individuals on a set of variables at different situations or time points. The two most common three-way component analysis techniques are PARAFAC ...
متن کاملModeling and analysis of a three-component piezoelectric force sensor
This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
متن کاملParametric three-way receiver operating characteristic surface analysis using mathematica.
Three-way receiver operating characteristic (ROC) surface analysis involves the calculation of a volume under an ROC surface (VUS), which is a measure of discriminatory accuracy of 2 diagnostic tests for 3 diseases. Nonparametric methods for calculating VUS and its standard error have been developed. The author presents the code for roc3D, a Mathematica computer program for performing parametri...
متن کاملIndependent component analysis for three-way data with an application from atmospheric science
In this paper, a new approach to independent component analysis (ICA) for three-way data is considered. The rotational freedom of the three-mode component analysis (Tucker3) model is exploited to implement ICA in one mode of the data. The performance of the proposed approach is evaluated by means of numerical experiments. An illustration with real data from atmospheric science is presented, whe...
