Thanks for all the attention we got for our collaborative publication, we’re now finally releasing the code to ensure reproducibility of the experiments. Feel free to reuse and adapt the code but please cite the source and above publication if you do so.

MLR and SVMLIGHT with MATLAB on MagnaTagATune:

The code used in this publication is split along the collaborators into two parts. MLR and SVMLIGHT were tested using a framework developed by Daniel Wolff at the MIRG group. You can download the code using subversion from the following repository:

user: anonymous
pass: citymirg
http://chivm.soi.city.ac.uk/svn/camir/branches/code_publications/ISMIR2012

For reproducing the results in the paper using Matlab follow these steps:

1. Download the code from above using a subversion client such as  collabnet svn
2. Edit the working directories in the startup.m file of the downloaded code
3. Start Matlab, change the working directory to the location of the downloaded code
4. Execute the startup file, this initialises the dataset and could take a few minutes.
5. Run the experiments using the scripts in core/magnatagatune/tests_evals (e.g. /mlr/mlr_fullstobgenrefeatures_fullsim_ISMIR12.m). This may take up to several hours depending on your machine.
6. The struct “out” should now contain the output results in out.mean_ok_test etc… For more detailed analysis run test_generic_display_results.m in the output directory

If you use this code please cite our paper. We are more than welcoming your additional bits of functionality to be included in the package.

The Similarity Data

The constraints we created from the processed similarity data, binned to 10-fold cross-validation, is available for download below. Each cell in the  xx_train and xx_test variables corresponds to one cross-validation fold. The columns in _train represent growing subsets, with the full training set in the last column of each row. In these cells, each matrix row  [a,b,c] corresponds to -> clip a more similar to clip b than to clip c
-> d(a,b) < d(a,c). Please cite the above paper when using any data from here.
