The problem of imbalanced domain learning has been thoroughly studied in the last two decades, with a specific focus on classification tasks. However, the research community has started to address this problem in other contexts such as regression, ordinal classification, multi-label and multi-class classification, association rules mining, multi-instance learning, data streams, time-series and spatio-temporal forecasting, text mining and multimodal data. Clearly, the research community recognises that imbalanced domains are a broad and important problem. Such a context poses important challenges for both supervised and unsupervised learning tasks, in an increasing number of real-world applications.

Tackling the issues raised by imbalanced domains is crucial to both academia and industry. To researchers, it is an opportunity to develop more adaptable and robust systems/approaches for very complex tasks. These tasks are, in many cases, those that industry is already facing today. These are very diverse and include the ability to prevent fraud, anticipate catastrophes, and in general to enable a more preemptive action in an increasingly fast-paced world.

This workshop proposal focuses on providing a significant contribution to the problems of learning with imbalanced domains, aiming to increase the interest and the contributions to solving its challenges. The workshop invites inter-disciplinary contributions to tackle the problems that many real-world domains face nowadays. With the growing attention that this challenge has collected, it is crucial to promote its further development in order to tackle its theoretical and application challenges.

- The maximum length for papers is 14 pages.
- All submissions must be written in English and follow the PMLR format. Instructions for authors and style files may be found here (link on website).
- All submissions will be reviewed by the Program Committee using a double-blind method. As such, it is required that no personal information or reference to the authors should be introduced in the submitted paper.
- Papers that have already been accepted or are currently under review for other workshops, conferences, or journals will not be considered.
- Submissions will be evaluated concerning their technical quality, relevance, significance, originality and clarity.
- Based on such evaluation, submissions will be graded with 4 (excellent contribution), 3 (interesting idea, minor issues), 2 (could improve) or 1 (needs extensive revision).
- All submissions graded with 4 and 3 will be invited for oral presentation and will be included in the workshop proceedings.
- Submissions graded with 2 will be invited for poster presentation and their inclusion in the workshop proceedings will be decided by the organising committee, based on recommendations by the respective reviewers.
- At least one author of each accepted paper must attend the workshop and present the paper.



All accepted papers will be included in the workshop proceedings, published as a volume in Proceedings of Machine Learning Research (PMLR). Additionally, based on the success of the workshop, authors of selected papers will be invited to submit extended versions of their manuscripts to a premier journal concerning the topics of this workshop.
