The problem of imbalanced domain learning has been discussed and studied for almost three decades. Although traditionally focused on classification tasks, the research community has started to address this problem in other contexts. These include multi-label and multi-class classification, regression, data streams, and many others. With an increasing number of real-world applications, we recognise the challenges posed by imbalanced domains as a broad and essential problem.

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 for 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 preemptive action in highly impactful and rare events in an increasingly fast-paced world.

This special issue welcomes contributions detailing significant advances regarding the current state of the art in imbalanced learning. Specifically, we welcome contributions concerning theoretical foundations of imbalanced learning, providing insights into issues raised by imbalanced domains and evaluation challenges. Also, we aim to bring together contributions that describe novel approaches to solving imbalanced learning problems, including for example pre and post-processing strategies and feature selection approaches.
