Book-Adaptive and Book-Dependent Models to Accelerate Digitization of Early Music

Optical music recognition (OMR) enables early music collections to be digitized on a large scale. The workflow for such digitisation projects also includes scanning and preprocessing, but the cost of expert human labour to correct automatic recognition errors dominates the cost of these other two steps. To reduce the number of recognition errors in the OMR process, we present an innovative application of maximum a posteriori (MAP) adaptation for hidden Markov models (HMMs) to build book-adaptive models, taking advantage of the new learning data generated from human editing work, which is part of any music digitization project. We also experimented with using the generated data to build book-dependent models from scratch, which sometimes outperform the book-adaptive models after enough corrected data is available. Our experiments show that these approaches can reduce human editing costs by more than half and that they are especially well suited to highly variable sources like early or degraded documents.

The Mental Representation of Music: A Neural Darwinist Perspective

In this presentation, I review the perceptual research related to auditory representation for music. The research suggests that multiple representations exist concurrently in the auditory system, and that the dominant representation is shaped by the specific auditory environment. I note that the research is consistent with theories of competitive representations, such as Edelman's neural Darwinist approach. I propose that the difference in predictive accuracy for different representations provides the feedback mechanism by which competing representations are selected. Repercussions for cognitive modeling of music are discussed.

Ethnomusicology of the Nineties: Perspectives of the History of Research

Bruno Nettl, rojen v Pragi leta 1930, je "profesor emeritus glasbe in antropologije" na University of Illinois, Urbana-Champaign, ZDA. Doktorat je pridobil na Indiana University. Čeprav je njegov domicil že desetletja University of Illinois, je kot gostujoči profesor deloval na številnih univerzah v ZDA in drugje po svetu. Prejel je vrhunske nagrade za dosežke s področij etnomuzikologije, muzikologije, antropologije in folkloristike Med njegove najpogosteje citirane knjige sodijo: North American Indian Musical Styles (1954); An Introduction to Folk Music in the United States (1960); Theory and Method in Ethnomusicology (1964); Folk and Traditional Music of the Western Continents (1965); Eight Urban Musical Cultures [ed.] (1978); The Study of Ethnomusicology: 29 Issues and Concepts (1983); The Western Impact on World Music (1985); The Radif of Persian Music: Studies of Structure and Cultural Context (1987); Blackfoot Musical Thought: Comparative Perspectives (1989); Comparative Musicology and Anthropology of Music: Essays on the History of Ethnomusicology [co-ed.] (1991); Excursions in World Music [co-ed.] (1992); New Perspectives on Improvisation [ed.] (1992); Heartland Excursions: Ethnomusicological Reflections on Schools of Music (1995); Encounters in Ethnomusicology, a Memoir (2002) and The Study of Ethnomusicology: 31 Issues and Concepts (2005).

Complex Systems Art Performance

The tasks of the artist in between this self-organizing process is firstly in the preparation of the used objects which are mostly liquids. The objects are put into physical relation in certain amounts and in certain configurations. This is equivalent to the initial state of the self-organizing.

Proceeding from this initial state develops the process of creating a form, while the artist can influence the self-organization by regulations, like for example adding new objects or physical reconfigurations of existing objects.

On The History of Ugliness

In “History of Beauty,” Umberto Eco explored the ways in which notions of attractiveness shift from culture to culture and era to era. With ON UGLINESS, a collection of images and written excerpts from ancient times to the present, he asks: Is repulsiveness, too, in the eye of the beholder? And what do we learn about that beholder when we delve into his aversions? Selecting stark visual images of gore, deformity, moral turpitude and malice, and quotations from sources ranging from Plato to radical feminists, Eco unfurls a taxonomy of ugliness. As gross-out contests go, it’s both absorbing and highbrow.
