改进的决策模型在手机垃圾短信过滤中的应用

摘要

A phone spam messages filtering is discussed. As the traditional phone filtering method uses the two-branch decision-making model, but causes a large decision loss, an improved decision-making model is put for ward, namely the three-branch decision-making model, then in theory, it proves the model causes less loss than the two-branch one , at last tries to apply the improved model into filter phone spam messages. The test result shows that the three-branch decision-making model actually causes less loss than the two-branch one, and gets better classification effect. So the three-branch decision-making model is superior and more effective.%研究手机垃圾短信过滤模型；针对于手机传统过滤方式采用了二枝决策模型引起较大决策损失的问题,提出了改进的决策模型-三枝决策模型；对改进的决策模型进行理论论证,证明三枝决策较二枝决策的决策损失更小,尝试将此改进模型应用于手机垃圾短信过滤实验；实验结果表明,三枝决策模型较传统的二枝决策模型在决策分类过程中产生错分率更低,决策更有效；通过对该模型的理论分析和实验证明,可知改进的三枝决策模型较传统的二枝决策模型风险损失小,分类效果更优.
