摘要:

我们研究了数据驱动的,先验的和随机的方法来划分标签空间的多标签分类与高斯朴素贝叶斯分类器的性能。在12个基准数据集上进行实验,并对5个已建立的分类质量指标进行评估:微观和宏观平均F1得分,子集准确度和汉明损失。数据驱动的方法明显优于随机基线的平均运行。在F1评分和子集准确度的情况下-在最差情况下,数据驱动方法比随机方法更有可能表现得更好。总有一种方法在最坏的情况下比先验方法表现得更好。数据驱动的方法对一个先验的方法与弱分类器的优势是小于当使用树分类器。

英文摘要:

We study the performance of data-driven, a priori and random approaches to label space partitioning for multi-label classification with a Gaussian Naive Bayes classifier. Experiments were performed on 12 benchmark data sets and evaluated on 5 established measures of classification quality: micro and macro averaged F1 score, Subset Accuracy and Hamming loss. Data-driven methods are significantly better than an average run of the random baseline. In case of F1 scores and Subset Accuracy - data driven approaches were more likely to perform better than random approaches than otherwise in the worst case. There always exists a method that performs better than a priori methods in the worst case. The advantage of data-driven methods against a priori methods with a weak classifier is lesser than when tree classifiers are used.
