==Welcome to MIREX 2026==
  
This is the main page for the 16th running of the Music Information Retrieval Evaluation eXchange (MIREX 2020). The International Music Information Retrieval Systems Evaluation Laboratory (IMIRSEL) at [https://ischool.illinois.edu School of Information Sciences], University of Illinois at Urbana-Champaign ([https://illinois.edu UIUC]) is the principal organizer of MIREX 2020.  
+
MIREX (Music Information Retrieval Evaluation eXchange) is an annual community evaluation campaign held in conjunction with the [https://ismir.net/ International Society for Music Information Retrieval Conference (ISMIR)]. This year, the conference will be held in [https://ismir2026.ismir.net/ Abu Dhabi, UAE] from November 8–12, 2026, and may include an online component.
  
The MIREX 2020 community will hold its annual meeting as part of [https://ismir.github.io/ISMIR2020/ The 21st International Society for Music Information Retrieval Conference], ISMIR 2020, which will be held in Montréal, Canada, October 11–15, 2020.
+
In a long run, we want to make MIREX a platform for researchers to share their latest research results, to compare their systems with others, and to promote the development of the field.

==Call for Challenges==
Director, IMIRSEL<br>
 
  
==Task Leadership Model==
+
We invite the ISMIR community to propose new research challenges that address cutting-edge problems in Music Information Retrieval (MIR). These challenges should aim to push the boundaries of current research and foster innovation in the field. We also welcome challenge sponsors from both industry and research institutions, particularly those willing to contribute datasets and computational resources to support the competition.
  
Like previous years, we are prepared to improve the distribution of tasks for the upcoming MIREX 2020.  To do so, we really need leaders to help us organize and run each task.
+
For the format and requirements for the challenge proposal, please go to [[2026:Call for Challenges]].
  
To volunteer to lead a task, please complete the form [https://forms.gle/9idWhxPgdisxFW55A here]. Current information about task captains can be found on the [[2020:Task Captains]] page. Please direct any communication to the [https://lists.ischool.illinois.edu/lists/admin/evalfest EvalFest] mailing list.
+
Task Captain Responsibilities:
  
What does it mean to lead a task?
+
* Register on the [https://www.music-ir.org/mirex MIREX Wiki] and maintain a task description page.
* Update wiki pages as needed
+
* Collect submissions via the MIREX submission server (or provide customized submission instructions).
* Communicate with submitters and troubleshooting submissions
+
* Execute and evaluate the submissions.
* Execution and evaluation of submissions
+
* Report results to MIREX and create a results page on the MIREX Wiki.
* Publishing final results
+
* (Optional) Present a MIREX task captain poster at the Late-Breaking and Demo (LBD) session at ISMIR 2026.
  
Due to the proprietary nature of much of the data, the submission system, evaluation framework, and most of the datasets will continue to be hosted by IMIRSEL. However, we are prepared to provide access to task organizers to manage and run submissions on the IMIRSEL systems.
+

MIREX is a community-based endeavour. Be a part of the community and help make MIREX 2020 the best yet.
 
  
===Mailing List Participation===
+
====Discord Server====
If you are interested in formal MIR evaluation, you should also subscribe to the "MIREX" (aka "EvalFest") mail list and participate in the community discussions about defining and running MIREX 2020 tasks. Subscription information at:
 
[https://mail.lis.illinois.edu/mailman/listinfo/evalfest EvalFest Central].
 
  
If you are participating in MIREX 2020, it is VERY IMPORTANT that you are subscribed to EvalFest. Deadlines, task updates and other important information will be announced via this mailing list. Please use the EvalFest for discussion of MIREX task proposals and other MIREX related issues. This wiki (MIREX 2020 wiki) will be used to embody and disseminate task proposals, however, task related discussions should be conducted on the MIREX organization mailing list (EvalFest) rather than on this wiki, but should be summarized here.  
+
For real-time discussion with the MIREX organizers or task captains, you may join our [https://discord.gg/vC2YWX29sC discord server].
  
Where possible, definitions or example code for new evaluation metrics or tasks should be provided to the IMIRSEL team who will embody them in software as part of the NEMA analytics framework, which will be released to the community at or before ISMIR 2020 - providing a standardised set of interfaces and output to disciplined evaluation procedures for a great many MIR tasks.
+
Notice: some task captains are not in the discord server.
  
===Wiki Participation===
+
====Repositories====
If you find that you cannot edit a MIREX wiki page, you will need to create a new account via: [[Special:Userlogin]].

Welcome to MIREX 2026

MIREX (Music Information Retrieval Evaluation eXchange) is an annual community evaluation campaign held in conjunction with the International Society for Music Information Retrieval Conference (ISMIR). This year, the conference will be held in Abu Dhabi, UAE from November 8–12, 2026, and may include an online component.

In a long run, we want to make MIREX a platform for researchers to share their latest research results, to compare their systems with others, and to promote the development of the field.

Call for Challenges

We invite the ISMIR community to propose new research challenges that address cutting-edge problems in Music Information Retrieval (MIR). These challenges should aim to push the boundaries of current research and foster innovation in the field. We also welcome challenge sponsors from both industry and research institutions, particularly those willing to contribute datasets and computational resources to support the competition.

For the format and requirements for the challenge proposal, please go to 2026:Call for Challenges.

Task Captain Responsibilities:

  • Register on the MIREX Wiki and maintain a task description page.
  • Collect submissions via the MIREX submission server (or provide customized submission instructions).
  • Execute and evaluate the submissions.
  • Report results to MIREX and create a results page on the MIREX Wiki.
  • (Optional) Present a MIREX task captain poster at the Late-Breaking and Demo (LBD) session at ISMIR 2026.

What's new:

In MIREX 2026, we introduce two special calls for challenges:

1. Novel evaluation pipelines

There is a growing need for new evaluation methodologies. We welcome challenge proposals that introduce novel evaluation pipelines, including but not limited to the evaluation of generative models, interactive systems, and other emerging paradigms.

2. Evaluation under limited resources

In addition to state-of-the-art systems, MIREX aims to better support researchers and research areas with limited resources. We welcome challenge proposals that focus on underrepresented research areas, music genres, or research communities.

Furthermore, all task captains are encouraged to report key resource indicators for each submission, including:

  • training data size
  • model size
  • other computational resources used in model development

See also the general Submission Guidelines.

  • Read the Participant Agreement and task description carefully.
  • Program your system.
  • Write a 2-4 page extended abstract PDF describing your system.
  • Submit your system and extended abstract to the MIREX submission site.
  • Top-performing teams will have the opportunity to present their MIREX posters at the LBD session at ISMIR 2026.

Important Dates

  • Challenge proposals due: May 15, 2026
  • Notification of acceptance: May 29, 2026
  • Submission open: Jul 1, 2026
