WebBrain-computer Interface (BCI) system based on motor imagery (MI) can provide more scientific and effective treatment solutions for SCI patients.MethodsAccording to the interaction between brain regions, a coherence-based graph convolutional network (C-GCN) method is proposed to extract the temporal-frequency-spatial features and … In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the … See more The coherence (sometimes called magnitude-squared coherence) between two signals x(t) and y(t) is a real-valued function that is defined as: $${\displaystyle C_{xy}(f)={\frac { G_{xy}(f) ^{2}}{G_{xx}(f)G_{yy}(f)}}}$$ where Gxy(f) is the See more Here we illustrate the computation of coherence (denoted as $${\displaystyle \gamma ^{2}}$$) as shown in figure 1. Consider the two … See more Coherence has been found a great application to find dynamic functional connectivity in the brain networks. Studies show that the … See more If the signals are non-stationary, (and therefore not ergodic), the above formulations may not be appropriate. For such signals, the concept of coherence has been extended … See more • Bicoherence • Scaled Correlation • Normalized cross-correlation See more

Coherence as resource in scattering quantum walk search on complete graph

WebCoherence is established by semantic connec- tions between sentences of a text which can be modeled by lexical relations. In this pa- per, we introduce the lexical coherence graph (LCG), a new graph-based model to represent lexical relations among sentences. WebSpecifically, heart coherence (also referred to as cardiac coherence or resonance) can be measured by HRV analysis wherein a person’s heartrhythm pattern becomes more ordered and sine wavelike at a … WebApr 9, 2014 · Coherence analysis can be detect for coordination of EEG rhythms between brain areas. It could not reflect the dynamic properties changing with time. Coherence analysis is a method developed on base of classic coherence analysis and signal's joint time-frequency representations in recent years.
