Objective: Churn prediction process on telecom industry is performed using background knowledge such as user information and application oriented constraints with the aim of clustering churn items of telecom communication users. Methods: This paper proposes Semi-supervised Constraint based Churn Clustering (SCCC) method. Semi-supervised learning method identifies different types of churns for labelled data items in telecom industry. PCK Mean based Clusteringwith Expectation Maximization (EM) algorithm finds cluster labels and distance metric for easy grouping of faults set. Similar types of issues are mapped with fast traversal procedure. Constraint based Cluster Membership achieves effective churns clustering by considering relative pairing of users. Findings: The proposed Semi-supervised Constraint based Churn Clustering (SCCC) method is implemented by using JAVA language. This JAVA language uses the code to effectively identify the churns in telecom industry. The SCCC method uses a churn dataset for conducting the experimental work.Experiment is conducted on the factors such as execution time, accuracy, clustering efficiency and support rate on predicting the churns in telecom industry. Experimental results show that the proposed Semi-supervised Constraint based Churn Clustering (SCCC) method out performs than the existing methods. Improvement: Proposed method is able to minimize the execution time, improve accuracy and clustering efficiency and also increase the support rate on predicting churns in telecom industry.
