基于不同权重的多标签分类器准确性评估方法
Weights-based accuracy evaluation method for multi-label classifier.
摘要
Abstract
Classification is one of the hotspots of data mining. The multi-label classifier can predict a set of labels for one data object. Data objects which have same attributes but their corresponding labels are different,and the number of them is imbalanced. The existing evaluation algorithm can not distinguish the cost. A weights-based accuracy evaluation method EMOWDIF(Evahiation Method Based on Weights Difference) is proposed. The weight is calculated according to the ratio of the multi-label instances, giving different rewards to the classifier,and can distinguish the performance of different classifiers effectively. It is programmed and used to evaluate the classification result. Experiments show the mothod can get a better performance on evaluating the classifier.关键词
