Where

• Nref is the number of non-zero elements in the ground truth data.
• Nsys is the number of active elements returned by the system.
• Ncorr is the number of correctly identified elements.

Overall Summary Results Task II

This subtask is evaluated in two different ways. In the first setup , a returned note is assumed correct if its onset is within +-50ms of a ref note and its F0 is within +- quarter tone of the corresponding reference note, ignoring the returned offset values. In the second setup, on top of the above requirements, a correct returned note is required to have an offset value within 20% of the ref notes duration around the ref note`s offset, or within 50ms whichever is larger. The Overlap ratio is calculated for an individual correctly identified note as File:Overlap.PNG
