Rule-based machine learning is a general term for any machine learning method that identifies, learns, or evolves "rules" to store, manipulate or apply knowledge. The defining characteristic of a rule-based machine learning algorithm is the identification and utilization of a set of relational rules that collectively represent the knowledge captured by the system. This is in contrast to other machine learning algorithms that commonly identify a singular model that can be universally applied to any instance in order to make a prediction.<ref>{{Cite journal|last=Bassel|first=George W.|last2=Glaab|first2=Enrico|last3=Marquez|first3=Julietta|last4=Holdsworth|first4=Michael J.|last5=Bacardit|first5=Jaume|date=2011-09-01|title=Functional Network Construction in Arabidopsis Using Rule-Based Machine Learning on Large-Scale Data Sets|journal=The Plant Cell|language=en|volume=23|issue=9|pages=3101–3116|doi=10.1105/tpc.111.088153|issn=1532-298X|pmc=3203449|pmid=21896882}}</ref> Rule-based machine learning approaches include [[learning classifier system]]s, association rule learning, and [[artificial immune system]]s.

基于强规则的原理,Rakesh Agrawal、 Tomasz imieli ski 和 Arun Swami 引入了关联规则这一概念,用于在超市销售点(POS)系统记录的大规模交易数据中发现产品之间的规则。例如,在超市的销售数据中发现的规则表明,如果某位顾客同时购买洋葱和土豆,那么他也很可能会购买汉堡肉。这些信息可以作为市场决策的依据,如促销价格或产品植入。除了市场篮子分析之外,关联规则还应用于 '''Web 使用挖掘 Web Usage Mining'''、'''入侵检测 Intrusion Detection'''、连续生产和'''生物信息学 Bioinformatics'''等应用领域。与序列挖掘相比,关联规则学习通常不考虑事务内或事务之间的先后顺序。

==== 归纳逻辑规划 ====
    
Inductive logic programming (ILP) is an approach to rule-learning using [[logic programming]] as a uniform representation for input examples, background knowledge, and hypotheses. Given an encoding of the known background knowledge and a set of examples represented as a logical database of facts, an ILP system will derive a hypothesized logic program that [[Entailment|entails]] all positive and no negative examples. [[Inductive programming]] is a related field that considers any kind of programming languages for representing hypotheses (and not only logic programming), such as [[Functional programming|functional programs]].

'''归纳逻辑规划 Inductive Logic Programming,ILP'''是一种用逻辑规划作为输入示例、背景知识和假设的统一表示的规则学习方法。如果将已知的背景知识进行编码,并将一组示例表示为事实的逻辑数据库,ILP 系统将推导出一个假设的逻辑程序,其中包含所有正面和负面的样例。归纳编程是一个与其相关的领域,它考虑用任何一种编程语言来表示假设(不仅仅是逻辑编程),比如'''函数编程 Functional programs'''。
