一种学习下降规则表的优化方法

An Optimization Approach to Learning Falling Rule Lists

Duke University(杜克大学)

Chaofan Chen, Cynthia Rudin

摘要:

下降规则列表是一种用于二进制分类的概率决策列表,由一系列“若-则”规则组成,其中前提在if子句中,而期望结果(“1”)的概率在then子句中。就像在常规决策列表中一样,规则在下降规则列表中的顺序很重要--每个示例都按其前件满足的第一个规则进行分类。与常规决策列表不同,下降规则列表要求期望结果(“1”)的概率沿列表单调递减。我们提出了一种学习下降规则列表和“软”下降规则列表的优化方法,以及使用最优解的边界来修剪搜索空间的蒙特卡罗搜索算法。

英文摘要:

A falling rule list is a probabilistic decision list for binary classification, consisting of a series of if-then rules with antecedents in the if clauses and probabilities of the desired outcome ("1") in the then clauses. Just as in a regular decision list, the order of rules in a falling rule list is important -- each example is classified by the first rule whose antecedent it satisfies. Unlike a regular decision list, a falling rule list requires the probabilities of the desired outcome ("1") to be monotonically decreasing down the list. We propose an optimization approach to learning falling rule lists and "softly" falling rule lists, along with Monte-Carlo search algorithms that use bounds on the optimal solution to prune the search space.
