Anyway, the number of the selected principle components, i.e., the required times of optimal filtering procedure, is usually much smaller than K, which is guaranteed by the prior assumption of sparse signal property.
In high SNR case, it is believable that the number of the selected principle components in step (b) of Table 2 is equal to the number of the actual sources; for lower SNR, the number of the selected principle components in step (b) of Table 2 may be slight larger than the number of the actual sources because the signal-subspace and the noise-subspace become undistinguishable.
Compared with the original IAA, EIAA can significantly reduce the computational burden thanks to the following facts: (1) In each iteration, the required times of optimal filtering procedure is equal to the number of the selected principle components in step (b) of Table 2.
The special argument device, which Rawls calls the "original position," is also deployed to select principles of individual conduct associated with the principles of justice, but these principles merely state that individuals should support just institutions.
Principles of justice are justified if they are selected by all parties to a properly specified choice situation, which Rawls argues will lead them to select principles of justice that will apply to all persons.
The parties behind the veil of ignorance must recognize that they are selecting principles of justice that, having been chosen, they must stick with in social life for good.
Having gained credibility by confirming these settled moral judgments, the original position then goes on to select principles for issues on which people's judgments may be less certain, such as how society should structure employment opportunities and what a just distribution of wealth and income might be.
Then a subset of the model's connection points are selected as mark points, also called watermark carriers, according to the mark point selecting principle.
A Kaiser-Guttman criterion was used to select Principle Components (PCs) for inclusion in subsequent analysis; i.e. those with eigenvalues greater than the average eigenvalue were retained.
