The learner model is responsible to record the cognitive process of a learner, and implemented by mapping the learner's hypothesis space and experiment space.

学习者模型记录了学习者的认知过程，映射着学习者问题空间中的假设空间和实验空间；

The two algorithms for concept learning efficiently complete the whole search through the hypothesis space based on a very useful structure: the general-to-specific partial order.

对于这两种算法来说，都是利用一般到特殊序的偏序结构来完成整个搜索过程。
