What happens when …

over 10 years of research in automatic music genre recognition is built upon tests and comparisons with a dataset rife with errors, such as replicas and mislabelings?

In the similarity matrix above, which I created with a simplified version of the Shazam fingerprint method (http://imi.aau.dk/~bst/software/index.html), we see several red squares showing that of the 100 excerpts in the Jazz category 13 are identical replicas. No cross-validation can cure that. Why hasn’t anyone listened to this dataset? (Or maybe someone has, but I cannot find such a discussion.)

Many more details to come…
