Marginal Distance and Hilbert-Schmidt Covariances-Based Independence Tests for Multivariate Functional Data.

Publication Type:Academic Journal

Source(s):Journal of Artificial Intelligence Research. 2022, Vol. 73, p1355-1384. 30p.

Abstract:We study the pairwise and mutual independence testing problem for multivariate functional data. Using a basis representation of functional data, we reduce this problem to testing the independence of multivariate data, which may be high-dimensional. For...

One-sided multivariate tests for high-dimensional data from two populations with unknown and unequal covariance matrices.

Publication Type:Academic Journal

Source(s):Songklanakarin Journal of Science & Technology. Jan/Feb2022, Vol. 44 Issue 1, p142-148. 7p.

Abstract:In this paper, we propose a new statistic for testing a one-sided hypothesis of mean vectors from two multivariate normal populations when the covariance matrices are unknown and unequal for high-dimensional data. As we know that the sample covariance ...

Uniform Detectability-Aided Boundedness Analysis of Error Covariances of Kalman Filter for Time-Varying Systems.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Systems, Man & Cybernetics. Systems. Aug2022, Vol. 52 Issue 8, p4798-4806. 9p.

Abstract:Some new results about the uniform lower and upper bounds of the predicted and filtered error covariances of the Kalman filter for linear time-varying systems from the perspective of uniform detectability are provided. First, a novel and general extend...

Parametric Methods for the Regional Assessment of Cardiac Wall Motion Abnormalities: Comparison Study.

Publication Type:Academic Journal

Source(s):Computers, Materials & Continua. 2021, Vol. 69 Issue 1, p1234-1252. 20p.

Abstract:Left ventricular (LV) dysfunction is mainly assessed by global contractile indices such as ejection fraction and LV Volumes in cardiac MRI. While these indices give information about the presence or not of LV alteration, they are not able to identify t...
