Oct. 12th @ Empress Crystal Hall, Victoria

Openning
Professor Stephen Downie gave the openning remarks:
- We will present certificates for participants. Feel free to grab yours if you are leaving.
- Appreciation to IMIRSEL team members.
Overview
- This year MIREX is highly successful. We got everything done on time!
- Matlab is widely used (universal retrieval language!)
- All the evaluation result data files are available on the wiki.
Tasks
- We had sub-tasks as tasks are getting matured.
- New tasks:
- Audio cover song: 13 different songs, each of which has 11 different versions
- Score following: have ground work done for future years
- QBSH: 48 ground truth melodies. Different versions of queries on the 48 melodies. About 2000 noise songs were selected from Essen dataset. Both audio input and MIDI input are supported.
- Please think about new tasks next year.
- New evaluations:
- Evalutron 6000 got real-world human judgment.
- Audio onset detection supported multiple parameters.
- Friedman test: It is valuable experience from TREC conferences, the annual contests in Text Retrieval area.
Onset Detection
By tuning the parameters, we can get an optimal setting which is a tradeoff between precision and recall. We need new dataset to see if the tuned parameters are good for onseen data. Question: comparison to last year results? Answer:
Evalutron 6000
Two judgments:
- category judgment: Not similar; Similar; Very similar
- continurous score: from 0 to 10, allowing one decimal after the decimal point.
- the system: using CMS open source software
- still have data that we haven't fully processed (other user/evaluator behaviors)
- new evaluation on other facets? e.g. mood
- suggestions?
- appreciate evaluators' volunteer work. Your work makes life beautiful!
Questions: consistency across users? Answer: the data appear to be quite consistency. More analysis can be done on the data which are publicly assessable.
- automatic evaluation using available metadata (vs human judgment)
Friedman tests
- a variation of chi-square test
- Matlab script code is on the wiki
- Compare different algorithms
- this test is conservative
Future MIREX plans
Discussion
- Encourage everyone to participate.
- Need data!
- Metadata: handy goundtruth
- reuse data: for at least two or three years
- submission: robustness, platform, scalability, paralellization

Kris: call for organizer! Alexandra Uitdenbogerd: "similarity" judgment is difficult. It might be easier to make judgment on genres for example. audience: How long was need for evaluate one pair? Stephen: we have the data, but have not digged into it. Bergstra: can you make the contests year around?
audience: please be aware of a work on labelling images? "EST game"? people playing games while labeling image. they went throught the IRB in CMU audience2: reaching some conclusions. To get some sense on what makes them different. Stephen: IPM journal will have a special issue on MIREX, I'd like to organize it by contests. There have been a lot of discussions going on on the mailing lists of Audio sim and symbolic melody similarity.
