认知评估是心理和教育测量中一个不断发展的领域，其中测试用于评估属性或技能的掌握/不足。一个关键问题是正确识别与测试中的项目相关的属性。在本文中，我们建立了一个数学框架下，理论性质可以讨论。我们建立了充分的条件，以确保每个项目所需的属性是从数据中学习。
Cognitive assessment is a growing area in psychological and educational measurement, where tests are given to assess mastery/deficiency of attributes or skills. A key issue is the correct identification of attributes associated with items in a test. In this paper, we set up a mathematical framework under which theoretical properties may be discussed. We establish sufficient conditions to ensure that the attributes required by each item are learnable from the data.
