A Roadmap Towards Versatile MIR
Emmanuel Vincent, Stanislaw A. Raczyński, Nobutaka Ono and Shigeki Sagayama
ABSTRACT – Most MIR systems are specifically designed for one appli- cation and one cultural context and suffer from the seman- tic gap between the data and the application. Advances in the theory of Bayesian language and information process- ing enable the vision of a versatile, meaningful and accu- rate MIR system integrating all levels of information. We propose a roadmap to collectively achieve this vision.
Wants to increase versatility of MIR systems across different types of music. Systems adopt a fixed expert viewpoint ( musicologist, musician). Have limited accuracy due to general pattern recognition techniques applied to a bag of features.
Emannuel wants to build an overarching scalable MIR system that successfully deals with the challenge on scalable unsupervised methods and refocuses MIR on symbolic methods. This is the core roadmap of VERSAMUS.
The aim of VERSAMUS is to investigate, design and validate such representations in the framework of Bayesian data analysis, which provides a rigorous way of combining separate feature models in a modular fashion. Tasks to be addressed include the design of a versatile model structure, of a library of feature models and of efficient algorithms for parameter inference and model selection. Efforts will also be dedicated towards the development of a shared modular software platform and a shared corpus of multi-feature annotated music which will be reusable by both partners in the future and eventually disseminated
