基于信息增益的紧致加权类关联规则挖掘

Compact Weighted Class Association Rule Mining using Information Gain

S. P. Syed Ibrahim, K. R. Chandran

摘要:

加权关联规则挖掘通过考虑项目的权重来反映项目的语义重要性。分类构造分类器并预测新的数据实例。提出了一种紧凑型加权类关联规则挖掘方法,将加权关联规则挖掘应用于分类中,构造了一种高效的加权关联分类器。该算法从数据集中选择一个非类信息属性,并基于该属性生成所有的加权类关联规则。在生成加权类关联规则时,将项目的权重作为参数之一。该算法使用HITS模型计算权重。实验结果表明,该系统生成的高质量规则数量较少,提高了分类精度。

英文摘要:

Weighted association rule mining reflects semantic significance of item by considering its weight. Classification constructs the classifier and predicts the new data instance. This paper proposes compact weighted class association rule mining method, which applies weighted association rule mining in the classification and constructs an efficient weighted associative classifier. This proposed associative classification algorithm chooses one non class informative attribute from dataset and all the weighted class association rules are generated based on that attribute. The weight of the item is considered as one of the parameter in generating the weighted class association rules. This proposed algorithm calculates the weight using the HITS model. Experimental results show that the proposed system generates less number of high quality rules which improves the classification accuracy.
