Generative Models as Descriptions
- If the model was used to create the sound, then it is an extremely compact and also exact description.
- Models represent a class of objects (ranging over their parameter space) - [Often the goal of search is not a specific document, but a related collection]
- The relationship between class members is proximity in a parameter space that can be semantic, rather than signal oriented.
- Analysis-by-Synthesis techniques exist wherein models participate in automatic classification of flat data.
