Embodiment Construction
[0085] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0086] Such as figure 1 As shown, a method for predicting student scores based on a fuzzy cloud cognitive diagnosis model provided by an embodiment of the present invention specifically includes the following steps:
[0087] Step S10, establishing a student cognitive cloud model.
[0088] In this embodiment, the "student cognitive cloud" is defined by introducing the cloud model theory, and the student cognitive cloud model is obtained by mathematically describing the student cognitive cloud model. The student cognitive state can be comprehensively and objectively described by using the student cognitive cloud model uncertainty and volatility.
[0089] Preferably, step S10 includes the following steps:
[0090] Ste...
