What
We modified the Spectral Clustering algorithm such that it identifies musical patterns (motives, sections, segments) of a piece.
How
It works like this:
- Obtain segments from a small scale layer (e.g. m > 8) using spectral clustering.
- Filter segments by keeping the repeated ones only (by using the label information).
- Repeat for N layers
- Aggregate patterns, because overlap is allowed in pattern discovery.
