Godfried T. Toussaint (Professor of Computer Science at the New York University in Abu Dhabi) joins Goldsmiths’ Summer Computing Seminars Series with a talk on measuring the complexity of vsual and auditory patterns.

When: 2pm – 3.30pm 6 June 2014
Where: Lecture Hall, Ground floor, Ben Pimlott Building, Goldsmiths
Cost: Free and open to the public

Abstract summary
A mathematical measure of pattern complexity based on the pattern’s sub-symmetries also correlates significantly with empirically-derived complexity measures of perception and production of auditory temporal and musical rhythmic patterns.

A sub-symmetry in a sequence is a subset of connected elements of the sequence that exhibits mirror symmetry. Not only does the sub-symmetry measure correlate highly with the difficulty of reproducing the rhythms by tapping after listening to them, but also the empirical measures exhibit similar behaviour, for both the visual and auditory patterns, as a function of the relative number of sub-symmetries present in the patterns.

This simple measure is also compared to the more complex measures of complexity, homogeneity, order, and symmetry proposed by F. Papentin & M. Krüger.
