一种计算代价敏感算法分类精度的方法
A method of classification accuracy calculation for cost sensitive algorithms
摘要
Abstract
Cost sensitive algorithms are widely applied to solve the problem of unbalanced classification.However,there is no objective evaluation criteria for cost sensitive algorithms.This paper proposes a method of classification accuracy calculation for cost sensitive algorithms.Balance accuracy is utilized instead of overall accuracy to effectively assess the performance of cost sensitive algorithms.Compared with overall accuracy,the proposed balance accuracy will not neglect the contribution of samples in small classes.In the experiment,we classified gene expression data with cost sensitive extreme learning machines.The result shows the balance accuracy is a valid criterion for evaluating classification performance.关键词
