分析学习
Machine learning, which includes empirical and analytic learning, is a key approach in knowledge acquisition. Empirical learning focuses on learning for classification (including learning rules from data for diagnosis). Analytic learning addresses learning for problem-solving tasks. Such tasks include planning, design, natural language understanding, control, and execution. There has been an explosion of work in machine learning in recent years. It is viewed as one of the key approaches of reducing the knowledge acquisition bottleneck. Learning using classification is one of the more mature machine-learning techniques. Classification algorithms take positive and negative instances and build classification trees that can be pruned to provide rules that represent the examples. Explanation-based learning (EBL) is a form of analytic learning that takes positive and negative examples and uses background knowledge (domain theory) to generate and generalize an explanation for the example.
机器学习技术可以从不同的角度进行分类。按照学习的综合属性，机器学习技术可分为归纳学习、分析学习、基于实例的学习、连接学习等。归纳学习是在给定关于某个概念的一系列已知的正例和反例的条件下，通过归纳推理得到对该概念的一般性描述的过程；决策树学习算法是目前广为应用的归纳学习算法，典型的决策树学习算法有CLS算法、ID3算法等。分析学习是利用先验知识并通过演绎推理来扩大训练样例提供的信息；在分析学习中，学习系统的输入除了训练样例和假设空间之外，还包括领域理论，它由可用于解释训练样例的先验知识组成。基于实例的学习需要把训练样例存储起来，泛化工作被推迟到分析新实例的时候；通常情况下，当基于实例的学习系统遇到新的实例时，它将分析新实例与以前存储的实例的关系，并据此把一个目标函数值赋给新实例；这种技术的优点是不在整个实例空间上一次性地估计目标函数，而是针对每个待分析新实例作出局部估计；该技术的一个不足是分析新实例所需的计算量可能比较大；所以，适当减少训练样例的数量，并有效地索引训练样例，以减少分析新实例时的计算量是一个重要问题。
