Geo-demographic analysis (GDA) is the study of geo-demographic that refers to spatial or geographical area, utilizing some spatial based analysis explicitly. Fuzzy Geographically Weighted Clustering (FGWC), a variant of Fuzzy C-Means (FCM), has been serving as an effective algorithm in Geo-demographic Analysis. FGWC is sensitive because of its initialization by determining random cluster centers makes...
In this paper, we propose a cluster-based optimization algorithm. It is a greedy agent-based tribal particle swarm optimization algorithm (GATPSO) which adapts the tribes by removing/generating particles and reconstructing tribal links in order to encourage better tribes to proliferate, and causes reducing the computation cost and preventing local optimal solutions. The proposed approach is applied...
Unsupervised models can provide supplementary soft constraints to help classify new data since similar instances are more likely to share the same class label. In this context, we investigate how to make an existing algorithm, named C3E (from Combining Classifier and Cluster Ensembles), more user-friendly by automatically tunning its main parameters with the use of metaheuristics. In particular, the...
