Workshop Topics

This half-day workshop aims to address the challenges and opportunities of learning from small data, focusing on methodologies that optimize the entire learning pipeline under data-scarce conditions. The workshop will bring together researchers and practitioners from diverse disciplines, including physics-informed machine learning, few-shot learning, in-context learning, data augmentation, active learning, semi-supervised learning, transfer learning, and experimental design and optimization. Additionally, we will explore the role of surrogate models, which reduce the need for extensive data collection by approximating expensive-to-evaluate functions, making them particularly useful in scenarios with limited data availability. These approaches, among other solutions for learning in data-scarce environments, will serve as the foundation for sharing innovative techniques, discussing best practices, and exploring the frontiers of learning from small data. By emphasizing techniques that minimize reliance on large data, the workshop seeks to inspire advancements in a range of fields where data is inherently limited or costly to obtain.

We invite contributions that introduce novel problem settings, propose groundbreaking methodologies, or share practical experiences in deploying systems designed to operate effectively with small data. Submissions that highlight interdisciplinary approaches or address domain-specific challenges in small data learning are particularly encouraged. Additionally, we welcome thoughtprovoking questions or critical perspectives that aim to spark discussion and push the boundaries of this important research area. In particular, we invite contributions that address aspects including, but not limited to:

Submission Instructions

We invite submissions of original work in the form of regular papers (8–16 pages) or extended abstracts (2–4 pages). All submissions will undergo a double-blind peer-review process, and accepted papers will be presented and discussed at the workshop. Extended abstracts are particularly suited for works-in-progress or industrial case studies. At least one author of each accepted paper is required to register for the conference and attend the workshop. 

We plan to publish the workshop proceedings with Springer, submissions will be made via CMT system of the ECML PKDD conference and the papers should be formatted in the (Lecture Notes in Computer Science ) LNCS style. Springer’s proceedings LaTeX templates are also available in Overleaf. 

Reviews are double-blind; papers must not include information that reveal the authors' identities.
