Sample entropy (SampEn) is a relatively simple and useful statistic to calculate for bedside data that effectively measures the quadratic entropy rate of the underlying physical time series process. Sample entropy has be en implemented as part of a mature neonatal heart rate monitoring system to ...
Entropy is a non-linear method derived from the theory of complex systems which measures the randomness and predictability of stochastic processes. Various types of entropy have been used in clinical monitoring20,21,22. Sample Entropy (SE) is a measure of complexity and regularity, defined as the...
In terms of the speed safety entropy under the condition of no fog (Figure6(a)), due to no warning information, there is no significant difference in the speed safety entropy among the three groups. The value range and average value of group ③ are the smallest. As for the acceleration ...
Sample entropy (SampEn) has been used to examine complexity or irregularity of heartbeat series. Nonetheless, the interpretation of nonlinear properties such as SampEn is not completely clear because there are only few studies referring to the nonlinear parameters of cardiovascular changes in different ...
Cross entropy was selected as a cost function. Forty neurons were found to be optimal in all the models. The training dataset (training set given to us) was divided into three sets viz., training, validation, and testing in the proportion of 60, 20, and 20%. The analysis was repeated ...
6. Parametric maximum entropy method can be used with this program. If a user desires an exact number of Lagrange multipliers, the minLagrange and maxLagrange parameter options can be set to equal values. For example, if the user knows the distribution is a Gaussian, then the user could ...
With respect to the selection strategy in the sample space, the performance metrics viz., accuracy, precision, and recall demonstrated that the query by committee, uncertainty sampling and entropy-based method gave the better overall performance for the classification of blueberry hardness than the ...
2.3. Spatial-dependence recurrence sample entropy Compared with the SampEn, SdrSampEn can capture the sequence information of time series. In this paper, SdrSampEn is used to evaluate the uncertainty of signal. And we proposed distinguishing noise-dominated IMFs from real signal-dominated IMFs metho...
It is difficult to take into account the entropy contribution to the free energy of the type ‘b’ ensemble of conformations with an integration protocol such as MCTI, whereas this is implicitly taken into account by a long free MD simulation (see Figure 10). In this particular case the cho...
