Abstract: K-means and its various hybrids are popularly used for software fault prediction. K-means++ is a hybrid clustering algorithm which overcomes major issue of getting stuck at local optima. Here, in this paper swarm intelligence-based hybrid techniques viz. cuckoo algorithm which improves the fitness function and bat algorithm which swarms with varying speeds are used on k-means++ algorithm to design a new hybrid clustering technique. KBat++ algorithm is a designed hybrid clustering technique with increased convergence rate which is further improvised using robust cuckoo swarm intelligent technique on this designed algorithm to generate CKBat++ algorithm which is predicted to generate optimised high-quality clusters. Experiments are performed using open-source UCI and promise datasets to implement and compare performance of designed algorithms with KBat and k-means++ algorithms. Accuracy, cluster quality check, CPU time etc. are used for performance comparisons. Results indicate that the designed technique which is used to predict and categorise software faults into faulty and non-faulty clusters to avoid errors and increase software reliability, is fairly better in performance than its counterparts.

Keywords: fault prediction; clustering; swarm intelligence; cuckoo algorithm; bat algorithm; k-means; k-means++ algorithm.
