Title: Three-Way Clustering in Machine Learning: Methods and Future Directions Abstract: Clustering is a fundamental machine learning technique that organizes unlabeled data into groups based on similarity. In many real-world scenarios, however, it is difficult to confidently assign certain data points to a specific cluster. To address this issue, soft clustering introduces probabilistic membership, allowing a data point to belong to multiple clusters with different degrees of likelihood.
Three-way clustering is a modern extension of soft clustering inspired by the theory of three-way decisions. Instead of assigning a data point strictly to a cluster or excluding it, three-way clustering introduces a third option representing uncertainty. Specifically, each data point is categorized as belonging inside a cluster, outside a cluster, or in a boundary region indicating partial membership.
Existing three-way clustering methods can generally be divided into two categories: evaluation-based approaches and operator-based approaches. Evaluation-based methods rely on membership functions to estimate the degree to which a data point belongs to a cluster and then determine its three-way assignment. In contrast, operator-based methods construct three-way clusters from traditional hard (two-way) clusters using a pair of operators.
In this talk, we introduce and review representative three-way clustering techniques and analyze their key characteristics. We also briefly discuss the historical development of three-way clustering and outline several promising directions for future research.
