==Welcome to MIREX 2026==
  
This is the main page for the tenth running of the Music Information Retrieval Evaluation eXchange (MIREX 2014). The International Music Information Retrieval Systems Evaluation Laboratory ([https://music-ir.org/evaluation IMIRSEL]) at the Graduate School of Library and Information Science ([http://www.lis.illinois.edu GSLIS]), University of Illinois at Urbana-Champaign ([http://www.illinois.edu UIUC]) is the principal organizer of MIREX 2014.  
+
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 2014 community will hold its annual meeting as part of [http://ismir2014.ismir.net/ The 15th International Conference on Music Information Retrieval], ISMIR 2014, which will be held in Taipei, Taiwan, the 27-31 October, 2014. The MIREX plenary and poster sessions will be held during the conference.
+
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.

To volunteer to lead a task, please add your name to the "Captains" column on the new [[2014:Task Captains]] page. Please direct any communication to the [https://mail.lis.illinois.edu/mailman/listinfo/evalfest EvalFest] mailing list.
+
==Call for Challenges==
  
What does it mean to lead a task?
+
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.
* Update wiki pages as needed
 
* Communicate with submitters and troubleshooting submissions
 
* Execution and evaluation of submissions
 
* Publishing final results
 
  
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.
+
For the format and requirements for the challenge proposal, please go to [[2026:Call for Challenges]].
  
We really need leaders to help us this year!
+
Task Captain Responsibilities:
  
==MIREX 2014 Deadline Dates==
+
* Register on the [https://www.music-ir.org/mirex 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.
  
This year, we have different deadlines for different tasks:

For task-specific questions, we have listed the email for each task captain [[MIREX_HOME#Task_Descriptions|here]].
Because MIREX is premised upon the sharing of ideas and results, '''ALL''' MIREX participants are expected to:
 
  
# submit a DRAFT 2-3 page extended abstract PDF in the ISMIR format about the submitted programme(s) to help us and the community better understand how the algorithm works when submitting their programme(s).
+
====Discord Server====
# submit a FINALIZED 2-3 page extended abstract PDF in the ISMIR format prior to ISMIR 2014 for posting on the respective results pages (sometimes the same abstract can be used for multiple submissions; in many cases the DRAFT and FINALIZED abstracts are the same)
 
# present a poster at the MIREX 2014 poster session at ISMIR 2014
 
  
===Software Dependency Requests===
+
For real-time discussion with the MIREX organizers or task captains, you may join our [https://discord.gg/vC2YWX29sC discord server].
If you have not submitted to MIREX before or are unsure whether IMIRSEL/NEMA currently supports some of the software/architecture dependencies for your submission a [https://docs.google.com/spreadsheet/viewform?formkey=dFpmNF9PUGdvd1o1OHVhMkZ4cXZvdkE6MA#gid=0 dependency request form is available]. Please submit details of your dependencies on this form and the IMIRSEL team will attempt to satisfy them for you.  
 
  
Due to the high volume of submissions expected at MIREX 2014, submissions with difficult to satisfy dependencies that the team has not been given sufficient notice of may result in the submission being rejected.
+
Notice: some task captains are not in the discord server.

If you are participating in MIREX 2014, 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 2014 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.
+
We are looking forward to seeing you at MIREX 2026!
  
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 2014 - providing a standardised set of interfaces and output to disciplined evaluation procedures for a great many MIR tasks.

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

How to Participate

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.
