As expected (see Tables 4 and 5), semi-quantification performance was superior for the PPMI dataset as compared to the local clinical database, reaching a maximum accuracy of 0.95 for PPMI and 0.87 for the local data.
However, when using the Southampton quantification method, performance is sensitive to the reconstruction and calibration strategy used.
Quantification of performance is difficult even with idealized data, and while measurements have been proposed such as the theoretical power to discover a single copy loss or gain [ 7], or the 'functional resolution' of the platform [ 6], these tend either to measure a very specific aspect of the platform, or appear flawed under close examination.
The quantification of the building performance is discussed by using stochastic finite element modeling techniques.
However, for sonars that have not been designed as scientific and research instruments, the quantification and verification of the system performance is of heightened importance, and should include how parameters such as the shape and gain of the beams vary with system and operational configurations.
To improve the damage quantification performance, the methodology is derived by eliminating erroneous assumptions in the existing modeshape-based methods and adopting additional modal information, i.e., natural frequencies.
For the ruffling analysis, the range of ratios within which each device executed the logic robustly was measured (the performance was assessed by quantification of the ruffling activity as described below).
It showed that the performance was drastically decreased in existence of quantification noise.
Analytical performance was evaluated in terms of specificity, linearity, limit of quantification, precision, accuracy, recovery and repeatability.
In the numerical verification, the damage quantification performance of the proposed method is compared with the performance of other existing methods.
