In the landscape of Artificial Intelligence (AI), the pursuit of Explainable AI (XAI) has predominantly thrived on methodologies reliant on labelled data, enabling the elucidation of model decisions in supervised settings. However, this reliance on annotated data presents a formidable challenge in unsupervised learning, where the absence of explicit labels renders traditional XAI techniques largely unfeasible. This specialized track aims to spotlight the intricate challenges and pioneering advancements crucial for unravelling the opaque workings of unsupervised learning systems. Unlike supervised approaches, unsupervised learning operates without explicit labels, posing a unique set of obstacles for applying conventional XAI methods, which heavily lean on annotated data for explanation generation. We cordially invite researchers, practitioners, and experts across diverse domains to delve into the complexities inherent in rendering unsupervised learning both transparent and interpretable. The goal is to foster discussions and explore methodologies that address the intrinsic opacity of unsupervised learning algorithms, seeking novel ways to provide meaningful explanations without the crutch of labelled data.
