Clustering is an unsupervised classification task in data mining, which partitions data set into certain number of clusters. Though many metaheuristics have been suggested to optimize clustering results, most of them are marred by the three key issues. First, clustering performance is devised on a single validity measure; hence, it produces a single best solution biased toward the criterion; it is...
This paper presents a non-dominated sorting based multi-objective artificial bee colony algorithm NSABC to solve multi-objective optimization problems. It is an extension of the artificial bee colony algorithm ABC, which is a single objective optimization algorithm, to the multi-objective optimization domain. It uses a novel approach in the employee bee phase to steer the solutions to simultaneously...
Web service composition is the process of assembling new services from the existing individual services. Due to the plenty of web services exhibiting similar functionality but different in terms of Quality-of-Service (QoS) requirements, the selection of an optimal service is a very crucial task. Consequently, the composition of web services with optimal QoS has become an important as well as the challenging...
The Tragedy of the Commons (TOC) is a social dilemma where rational and self-interested agents utilizing a shared resource of fixed capacity leads to inefficient utilization of the resource. In any society, two crucial aspects: individual and social concerns, are responsible for the ineffective performance of the system as well as the individual. Since these two aspects create a dilemmatic situation...
This paper compares performance of the artificial bee colony algorithm (ABC) and the real coded genetic algorithm (RCGA) on a suite of 9 standard benchmark problems. The problem suite comprises a diverse set of unimodal, multimodal and rotated multimodal numerical optimization functions and the comparison criteria include (i) solution quality, (ii) convergence speed, (iii) robustness, and (iv) scalability...
Association rule mining along with frequent items has been comprehensively research in data mining. In this paper, we proposed a model for association rules to mine the generated frequent k-itemset. We take this process as extraction of rules which expressed most useful information. Therefore, transactional knowledge of using websites is considered to solve the purpose. In this paper we use interestingness...
In this paper, we determine the empirical comparison of Apriori and FP-growth algorithm for frequent item set sequences for Web Usage data. We define the data structure, its implementation and algorithmic features mainly focusing on those that also arise in frequent item set mining. Web usage mining itself can be defined further depending on the type of usage data is considered like web server data,...
