Abstract

The invention discloses a model detection method based on deep learning student online learning efficiency prediction. The method comprises the steps of obtaining original data and features, determining a student learning state, determining an action state track sequence, constructing a Markov decision process model, generating a PRISM code, determining action state transition and processing a migration action result. In the construction of the Markov decision process model, the transition probability Pi, j is used to construct the Markov decision process model, so that the construction steps are simplified, the complex calculation process is reduced, and the operation speed is improved; the Markov decision process model detection is used for student online learning efficiency prediction, so that the change of the learning efficiency of students can be accurately predicted. The method has the advantages of being simple, high in operation speed and the like, and can be used for predicting the online learning efficiency of students in network education.

Description

technical field [0001] The invention belongs to the field of model detection in computer technology, and in particular relates to a model detection method for predicting students' online learning efficiency based on deep learning. Background technique [0002] In the online learning industry, the most important thing is to evaluate the quality of students' learning. Existing software mainly uses exams to evaluate the quality of students' learning. However, the learning quality results obtained through examinations lag behind in terms of time. Therefore, there is a need for real-time assessment of learning quality methods to improve the educational quality and student acceptance of online education. [0003] At present, many schools choose online teaching, and the effect of online learning is uneven. It is necessary to use the prediction method of students' online learning efficiency to improve the learning quality of students' online learning. Contents of the invention ...
