Three-way Clustering in Machine Learning

Clustering, a machine learning technique, organizes unlabeled data points into distinct groups based on their similarities. However, in numerous scenarios, confidently assigning specific data points to particular clusters becomes challenging. Soft clustering addresses this challenge by introducing a probability factor, indicating the likelihood of a data point belonging to different clusters. Three-way clustering is a modern extension of soft clustering rooted in the concept of three-way decisions. Specifically, each data point is allocated a value that indicates whether it belongs inside, outside, or partially inside a cluster. There are two types of three-way clustering techniques, namely evaluation-based approaches and operation-based approach. The evaluation-based approaches rely on a membership function to calculate the degree of a data point belonging to a cluster. The operator-based approaches use a pair of operators to construct a three-way cluster from a hard two-way cluster. We will introduce, review, and analysis various three-way clustering techniques in this talk. In addition, history of three-way clustering and future development of three-way clustering will also be discussed.
