Methods of machine learning are approaching their limits whenever training data of a high quality are scarce. The potential reasons for data scarcity are manifold: limited capabilities of human supervisors and processing systems, a need for early predictions which can later be refined, or transfer settings where the only available data stem from some different learning task. Situations like these demand methods that improve the overall life-cycle of machine learning models, including interactions with human supervisors, interactions with other processing systems, and adaptations to different forms of data that become available at different points in time. This demand includes techniques for evaluating the impact of additional resources (e.g., data) on the learning process; strategies for actively selecting information to be processed or queried; techniques for reusing knowledge over time, across different domains or tasks, by recognising similarities and by adapting to changes; and methods for effectively using different types of information, like labeled and unlabeled data, constraints, and knowledge. Techniques of this kind are being investigated, for example, in the areas of adaptive, active, semi-supervised, and transfer learning. While these investigations often happen in isolation of each other, real use cases of machine learning require interactive and adaptive systems that operate under changing conditions and address the challenges of volume, velocity, and variability of the data. This combination of a workshop and tutorial will continue to stimulate research on systems that combine multiple areas of interactive and adaptive machine learning, by bringing together researchers and practitioners from these different areas. We welcome contributions that present a novel problem, propose a new approach, report practical experience with such a system, or raise open questions for the research community.

The event continues a successful series of workshops and tutorials at ECML-PKDD 2017 in Skopje (Workshop & Tutorial), IJCNN 2018 in Rio (Tutorial), ECML-PKDD 2018 in Dublin (Workshop), ECML-PKDD 2019 in Würzburg (Workshop & Tutorial), ECML-PKDD 2020 (hosted in Ghent, online Workshop), ECML-PKDD 2021 (hosted in Bilbao, online Workshop), ECML-PKDD 2022 in Grenoble (Workshop), and ECML-PKDD 2023 in Torino (Workshop).

The half-day workshop evolves around techniques and approaches for optimising the whole learning process, including the interaction with human supervisors, processing systems, and includes adaptive, active, semi-supervised, and transfer learning techniques, and combinations thereof in interactive and adaptive machine learning systems. Our objective is to bridge the communities researching and developing these techniques and systems in machine learning and data mining. Therefore, we welcome contributions that present a new problem setting, propose a novel approach, or report experience with the practical deployment of such a system and raise unsolved questions to the research community. In particular, we welcome contributions that address aspects including, but not limited to:
