PSO based Swarm Intelligence Technique for Multi- Objective Classification Rule Mining

Anil Kumar
2016 International Journal of Computer Applications  
The existing methodologies can't cope of with such complex problems. This paper presents classification rule mining as a multi-objective problem rather than a single objective one.  ...  In the rule extraction phase, a large number of classification rules are extracted from training data. This phase is based on two rule evaluation criteria: support (coverage) and confidence.  ...  Partial classification is the classification of a particular single class from all the other classes. Similar formulation to [20] were used to search for Pareto-optimal association rules [21] .  ...

Most recent work has been focused on associative classification technique. Most research work of classification has been done on single label data.  ...  Multi-label classification is an extension of single-label classification, and its generality makes it more difficult to solve compare to single label.  ...  Whilst single-label classification, which assigns each rule in the classifier the most obvious class label, has been widely studied [9] little work has been conducted on multi-label classification.  ...
