The European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases will take place in Bilbao, Basque Country (Spain), from the 13th to the 17th of September 2021.

This event is the premier European machine learning and data mining conference and builds upon over 19 years of successful events and conferences held across Europe.

The journal track of the conference is implemented in partnership with the Machine Learning Journal and the Data Mining and Knowledge Discovery Journal. The conference provides an international forum for the discussion of the latest high-quality research results in all areas related to machine learning, data mining, and knowledge discovery.


Eligibiliy criteria:
Papers on all topics related to machine learning, knowledge discovery and data mining are invited. However, given the special nature of the journal track, only papers that satisfy the quality criteria of journal papers and at the same time lend themselves to conference talks will be considered. Consequently, journal versions of previously published conference papers or survey papers will not be considered for the special issue. Note that a paper rejected by the Machine Learning Journal should not be submitted to the Data Mining and Knowledge Discovery Journal and vice versa. Papers that do not fall into the eligible category may be rejected without formal reviews. Rejected papers from the journal track can be submitted to the conference.

Authors are encouraged to adhere to the best practices of Reproducible Research (RR), by making available data and software tools for reproducing the results reported in their papers. For the sake of persistence and proper authorship attribution, we require the use of standard repository hosting services, e.g. dataverse (https://dataverse.org/), mldata (https://www.mldata.io/datasets/), openml (https://www.openml.org/ for data sets, and mloss (http://mloss.org/software/), bitbucket (https://bitbucket.org/), github (https://github.com/) for source code.

Authors who submit their work to the ECMLPKDD special issues of these journals commit themselves to presenting their paper at the ECMLPKDD conference if it is accepted. Note that for the earlier deadlines, this is likely to be ECMLPKDD 2021 but for the later deadlines this may be a later edition of the conference.


Reviewing:
The journal track allows continuous submissions from September 2020 to early May 2021. Papers will be processed and sent out for review after each of the following cutoff dates:

September 20, 2020
November 22, 2020
January 31, 2021
May 2, 2021
(note that papers submitted by this last deadline cannot possibly be accepted in time for ECMLPKDD 2021)

The deadline on each of these dates is 23:59, Central European Time. We strive for a high quality and efficient review process. For each submission, we aim at obtaining three reviews from experienced reviewers, including members of the Guest Editorial Board. Our goal is to arrive at an initial decision about 10 weeks after each cutoff date, though meeting this target may not always be possible. After the initial review phase, many papers will require substantial revisions, and the revised paper will be re-reviewed, which extends the review process. Consequently, a paper’s chance of finishing the review cycle and being included in the ECMLPKDD 2021 special issue decreases with each subsequent cutoff date. This means that accepted papers, especially those that were submitted to the later deadlines, may be included in the ECMLPKDD 2022 (or even later) special issue (and subject to approval of the ECMLPKDD steering committee and future Journal Track Chairs). The reviewing process is single-blind.


Submission Procedure:
To submit to this track, authors have to make a journal submission to either the Springer Data Mining and Knowledge Discovery journal or the Springer Machine Learning journal (no paper can be submitted to both), and select the type of submission to be for the ECMLPKDD 2021 special issue. It is highly recommended that submitted papers do not exceed 20 pages including references. Every paper may be accompanied with unlimited appendices.

The papers should be formatted in the Springer journal style (svjour3, smallcondensed). Both journals require authors to include an information sheet (for Machine learning submissions) or a cover letter (up to 2 pages) as a supplementary material (for Data Mining and Knowledge Discovery submissions) that contains a short summary of their contribution and specifically address the following questions:

What is the main claim of the paper? Why is this an important contribution to the machine learning/data mining literature?
What is the evidence provided to support claims? Be precise.
Report 3-5 most closely related contributions in the past 7 years (authored by researchers outside the authors’ research group) and briefly state the relation of the submission to them.
Who are the most appropriate reviewers for the paper? Authors are required to suggest up to four candidate reviewers (especially if external to the Guest Editorial Board), including a brief motivation for each suggestion.
Optionally, list up to four researchers/potential reviewers with competing interests that should not be considered for reviewers.


The conference will take place at the Euskalduna Conference Centre which is located in the heart of Bilbao, close to the famous Guggenheim museum. Euskalduna is a unique building and one of the flagships of new, 21st century Bilbao. Opened in 1999, it has been recognized as one of the most important Works in contemporary architecture. It was also distinguished as the World ́s Best Congress Centre in 2003.
