推理单元 meaning in English

reasoning element

When a new problem is came up we abstract it into a new case and find a old similar case from the case base . so we can get some useful suggestions from the old case . if the old case is not fit to the new case , then we adapt the old one to fit the new condition . if this is successful the adapted case is stored into the case base and when the same condition comes up again we will get some useful information from this stored case
Cbr ( case - basereasoning )是一种人工智能的推理方法，它以实例作为其最基本的推理单元，当一个新的待解决问题提出以后，我们可以把它抽象为一个新实例，为了解决这个问题我们从实例库中找出一个和新实例最相近的实例，其解决方案就可作为新问题的参考，如果对此方案有什么不满意，可进行修改，修改后的实例成为一个新学习到的实例被存到实例库中，如果下一次碰到类似的问题就可以此作为参考。
