Possibilistic fuzzy C-means clustering under observer-biased framework

Abstract

Ensuring an adaptable and interactive tools to analyze data objects is an advisable objective of machine learning algorithms. Many methods exist, and new methods, or improvements in existing ones are proposed regularly to deal with a variety of problems in different areas. We develop a variant of the well-known Possibilistic Fuzzy c-Means Clustering algorithm PFCM that takes into account the observer-biased framework, Possibilistic fuzzy c-means with focal point PFCMFP. the accuracy of the proposed method is verified by cluster validity measures. The experimental results have shown that the accuracy of the new method increases significantly, compared to the initial PFCM algorithm. To elaborate this study, we have used a dataset of individual household electric power consumption, that is accessed publicly at the UCI Machine Learning Repository.
