Comparison of relative error
between Kriging method and BPNN, (a) temperature at flow front and (b) confluence angle.
Figure 5 shows (a) a comparison of the calculated and measured PHS values and (b) the corresponding relative error
In the section 4, we give the definitions of conditional filtering noise and expected data utility based on the absolute value of relative error
. Then we present adaptive Gaussian mechanism, it can achieve the expected data utility of noise response results, while satisfying differential privacy.
Mean relative error
, mean estimated error and chi-squared test were calculated for each mathematical model using the following expressions, respectively:
A CMOS controllable constant power generator based on the resistive mirror  has the range of generated power from 0.48 mW to 10.8 mW, and the load resistance dynamic range up to 28, with the relative error
of generated power less than 2.2% and the supply voltage of 10 V.
According to Table 5, the relative error
of the envelope method proposed in this paper is slightly greater than that of the direct method because the data points positioned by the envelope method are not on the simulation current curve, which results in the deviation between the locations of the envelope change points and the actual signal change points.
The charts presenting cumulative frequency of relative errors
on estimating regulated pressure enable quantification of the accuracy of the proposed model.
where RE(i) is the relative error
of sample i, [C.sub.cu-max](i) and [C.sub.cu-min](i) are the maximum and minimum inversion values, respectively, of the copper ion content for sample i when the water content changes among the six values described above, and [C.sub.cu-mes](i) is the measured value of the copper ion content for sample i.
To estimate sensitivity of differences we have used relative error
. Relative error
[[DELTA].sub.j] % of j-th performance indicator, can be calculated using following expression:
To be consistent with Plot (b) in Figure 2, where the relative error
has been represented on the spatial interval -4 [less than or equal to] x [less than or equal to] 1, here we keep the same interval to plot the relative error
Here, the constants c and n denote the cost and relative error
of the starting simulation, respectively.
