This paper is a contribution to the formalisation of Thagard’s coherence theory. The term coherence is defined as the quality or the state of cohering, especially a logical, orderly, and aesthetically consistent relationship of parts. Cognitive coherence in particular is the coherence theory based explanation of the mind which evaluates the truth of a cognition in terms of it being a member of ...

We present on the method of inverse coherence matrix for the estimation of network connectivity from multivariate time series of a complex system. In a model system of coupled chaotic oscillators, it is shown that the inverse coherence matrix defined as the inverse of cross coherence matrix is proportional to the network connectivity. Therefore the inverse coherence matrix could be used for the...

Models for the distribution of the wall-pressure under a turbulent boundary layer often estimate the coherence of the cross-spectral density in terms of a product of two coherence functions. One such function describes the coherence as a function of separation distance in the meanow direction, the other function describes the coherence in the cross-stream direction. Analysis of data from a larg...

In the past we proposed a multidimensional speckle noise model to which we now include systematic phase variation effects. This extension makes it possible to define what is believed to be a novel coherence model able to identify the different sources of bias when coherence is estimated on multidimensional synthetic radar aperture (SAR) data. On the one hand, low coherence biases are basically ...

This paper was motivated by the desire to improve the effectiveness of retrieving images on the basis of their color content by improving the Color Coherence Vector method. There is a growing demand for efficient and effective image retrieving techniques from the huge multimedia databases on the Internet and from the image libraries. In this paper three methods have been proposed and developed ...

Experimental studies of how juries reach their verdicts in court strongly suggest that coherence reasoning is ubiquitous in judicial reasoning. Under massive cognitive pressure to process large numbers of conflicting pieces of evidence and witness reports, jury members base their judgment on an assessment of the most coherent account of the events. From a normative perspective, the legitimacy o...

We establish an operational theory of coherence (or of superposition) in quantum systems. Namely, we introduce the two basic concepts — “coherence distillation” and “coherence cost” in the processing quantum states under so-called incoherent operations [Baumgratz/Cramer/Plenio, Phys. Rev. Lett. 113:140401 (2014)]. We then show that in the asymptotic limit of many copies of a state, both are giv...
