摘要:

提出了一种替代当前主流预处理方法的方法:值选择(VS)。与现有的方法不同,例如删除特征的特征选择和消除实例的实例选择,值选择消除数据集中的值(相对于每个特征),有两个目的:减少模型大小和保持其准确性。提出了两种基于信息论度量的概率方法:PVS和P + VS。这些结果与现有的预处理方法,如特征选择,特征变换,和实例选择方法进行了比较。实验结果表明,该方法能够在精度和模型规模缩减之间取得平衡.

英文摘要:

An alternative to current mainstream preprocessing methods is proposed: Value Selection (VS). Unlike the existing methods such as feature selection that removes features and instance selection that eliminates instances, value selection eliminates the values (with respect to each feature) in the dataset with two purposes: reducing the model size and preserving its accuracy. Two probabilistic methods based on information theory's metric are proposed: PVS and P + VS. Extensive experiments on the benchmark datasets with various sizes are elaborated. Those results are compared with the existing preprocessing methods such as feature selection, feature transformation, and instance selection methods. Experiment results show that value selection can achieve the balance between accuracy and model size reduction.
