Abstract
En 中文
Semi-supervised learning is significant data analysis method in the age of Big Data. The Bayesian-based classifier is a classical classification method in semi-supervised learning. Wherein, the classifier with clustering and classification technology have experienced the transformation from sequential structure to simultaneous structure. There are two main difficulties in simultaneous structure: the limited accuracy and diversity caused by rigid optimization algorithm; and the imbalance status between clustering and classification processes caused by insufficiently structure. To overcome these difficulties, a novel multi-objective differential evolution and firework algorithm for automatic simultaneous clustering and classification algorithm (MASCC-DE/FWA) is proposed. The main contributions of MASCC-DE/FWA contain: (1) Combination searching strategy for dynamic searching (2) Rapid and low-complexity silhouette coefficient as redesigned clustering objective function (3) Automatic clustering, opposition-based learning and adjusted mutual information for strengthening SCC-MOEA framework. The experimental result demonstrates that MASCC-DE/FWA performs better than other 8 state-of-art classification algorithms on synthetic dataset, 19 UCI datasets and image segmentation tasks.
