Abstract

Big data refers to the massive quality of data being generated at a drastic speed from various heterogeneous sources namely social media, mobile devices, internet transactions, networked devices, and sensors. Several data mining (DM) and machine learning (ML) models have been presented for the extraction of knowledge from Big Data. Since the big datasets include numerous features, feature selection techniques are essential to eliminate unwanted and unrelated features which degrade the classification efficiency. The adoption of DM tools for big data environments necessitates remodeling the algorithm. In this aspect, this paper presents an intelligent feature subset selection with fuzzy wavelet neural network (FSS-FWNN) for big data classification. The FSS-FWNN technique incorporates Hadoop Ecosystem tool for handling big data in an effectual way. Besides, the FSS-FWNN technique involves three processes namely preprocessing, feature selection, and classification. In addition, quasi-oppositional chicken swarm optimization (QOCSO) technique is employed for the feature selection process and the FWNN technique is applied for the classification process. The design of QOCSO algorithm as an FS technique for big data classification shows the novelty of the work and the feature subset selection process considerably enhances the classification performance. An extensive set of simulations is carried out and the results are reviewed in terms of several evaluation factors in order to analyse the improvement of the FSS-FWNN approach. The experimental findings demonstrated that the FSS-FWNN approach outperformed the most current algorithms.
