TOPS can reduce those degradations by using the certain signal subspace obtained from the estimated correlation matrix instead of the steering vector of the frequency band.
PCA was conducted using the correlation matrix instead of the covariance matrix to account for the differences in measurement scales between the three variables.
On the other hand, the method can be regarded as an improvement to the SOBI-based modal identification method because it uses the Hankel matrix instead of the covariance matrix of response to perform the JAD.
The coherence and the tightness of A ~ do not change if we select the rows from the DFT matrix, instead of the IDFT matrix.
Diagonal LDA (dLDA [ 30]) is a simple modification of linear discriminant analysis, which implies that we use the pseudoinverse of the covariance matrix instead of the actual inverse.
To circumvent this problem, a square-root filter can be considered to propagate the square root of the covariance matrix instead of the covariance itself [33, 34].
RBF centers for the RBFNN model thus can be determined very quickly by calculating the principal components of the data matrix instead of the iterative calculation process of k-means clustering.
We have chosen to normalise the covariance structure matrix instead of the scale parameter in our work, because of the analogy between the average scale,, and the radar cross section,, of 1-dimensional data (also described in [8]), even though this interpretation is not straight forward for multidimensional data.
end{cases} (36) The idea is also similar to that of [22, 23], which uses the symmetric positive semi-definite matrix instead of the identity matrix in the proximal term.
In this paper, I propose a new method to address this issue by 1) adjusting the pedigree-based relationship matrix to be compatible with the marker-based relationship matrix instead of the reverse and 2) extending the single-step genetic evaluation using a joint likelihood of observed phenotypes and observed marker genotypes.
