Beyond Coherence
Much has happened since the 1960s and 1970s when the idea of self-organization emerged and began to alter our conceptions of human nature, of social organization, and of a social science that had heretofore been wedded to linear causal explanations. The experience that systems could organize themselves has been revolutionary and constitutes a paradigm shift that is still ongoing. In the followi...
متن کاملBeyond Coherence : Recovering Structured Time - Frequency Representations
We consider the problem of recovering a structured sparse representation of a signal in an overcomplete time-frequency dictionary with a particular structure. For infinite dictionaries that are the union of a nice wavelet basis and a Wilson basis, sufficient conditions are given for the Basis Pursuit and (Orthogonal) Matching Pursuit algorithms to recover a structured representation of an admis...
متن کاملDe Finetti Coherence and Beyond
The aim of the tutorial is to present the concept of coherence, which dates back to de Finetti, showing its role in managing incomplete (or missing) information. We will start recalling the notion of coherence for (unconditional) probabilities and the related fundamental theorem. Then, in order to generalize this notion to assessments on a set of conditional events, the axiomatic definition of ...
متن کاملBallistic attenuation of low-coherence optical fields.
Using a novel experimental geometry, we measured the ballistic attenuation of low-coherence optical fields propagating in multiple-scattering media. The high dynamic range and the angular filtering capability permit detecting the ballistic component through random media thicker than 20 mean free paths. Owing to the accuracy of the technique, we observe deviations from the standard Lambert-Beer ...
