In this study, we introduced a new metric named local similarity based on waveform cross-correlations on spatially close stations for large-N arrays.
BFC discriminates patterns based on waveform, phase and amplitude.
A probability value is calculated for each partition to determine the entropy based on Shannon's entropy [ 28]. 4. Parametric graph entropy measures called Dehmer-entropy: To determine the entropy, measures of this class [ 8, 10], assign a probability value to each vertex of a graph, using so-called information functionals (IFs).
Therefore, it meets the need for seismologists to be able to select waveform data based on seismic waveform features as well as sensor geolocations and temporal specifications.
This definition of entropy is based on Shannon's entropy, which is a standard measure for estimating the uncertainty of a given signal in Information Theory (Schneider 2010).
Nicolaou, N. & Georgiou, J. Detection of epileptic electroencephalogram based on Permutation Entropy and Support Vector Machines.
Like in conventional ex-post analysis based on estimated entropy, high entropy values characterize unpredictable series, while more stable series exhibit lower entropy values.
This method is based on four entropy features for classification: phase entropy 1 (S1), phase entropy 2 (S2), approximate entropy (ApEn), and sample entropy (SampEn).
This is based on the relationship existing between entropy and exergy, either for heat interaction (thermal exergy based on thermal entropy) or for work interaction (mechanical exergy based on mechanical entropy).
Based on Table 9, alternative number 9 i.e., 360 Degree has been selected as the optimal PA method based on MULTIMOORA, Entropy MULTIMOORA, and Entropy TOPSIS.
