Webb10 jan. 2003 · In order to numerically gauge the disorder content of laughter frequencies, we have performed several "entropy" measures of the spectra –trying to unambiguously identify spontaneous laughter from "faked", articulated laughter. Interestingly, Shannon’s entropy (the most natural candidate) performs rather poorly. Webb7 jan. 2024 · In information theory, Shannon entropy is one of the best known methodologies to measure the uncertainty.

WebbThe “Shannon entropy” is a concept introduced by Shannon (1948), where a measure of the uncertainty of occurrence of certain event, given partial information about the system, is proposed.
