Embodiment Construction

[0058] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] The technical solution of the present invention will use the method of RNN to track the knowledge state of the students. And encode information such as the general description of the students' past learning records, the description of the current learning scene, etc., and the resulting code becomes a general code. And using the factorization machine (Factorization Machine, FM) method, combined with the obtained generalized coding and student...

Abstract

The invention provides an intelligent teaching system based on deep learning, and the system comprises a learning record obtaining module which is used for obtaining learning records from a database, and the related information comprises student numbers, test question numbers, related knowledge points, answering results, and answering time; and a scene coding module which is used for summarizing, summarizing and coding past learning records and current scenes of the students to obtain general codes. A learning sequence coding module which is used for coding previous learning sequences of the knowledge points by the students to obtain knowledge point answering codes; a neural network training module which is used for training a neural network according to the general bracket codes and the knowledge point answer codes; a prediction module which is used for predicting the answering result of the student in a given scene; and a learning scheduling module which is used for recommending learning contents to the students according to prediction of the answering results of the students.

Description

technical field [0001] The invention relates to the technical fields of knowledge tracking, intelligent teaching aid system, and artificial intelligence, in particular, a prediction technology based on deep learning for mastering students' knowledge points. Background technique [0002] In today's society, students are under a lot of pressure to study. Intelligent Tutoring System (ITS) is a system that intelligently and individually arranges students' learning and improves students' learning efficiency. Students have autonomy in learning information technology. They have different study schedules and do not need to study the same material. All of this needs to be based on accurate tracking of changes in students' knowledge levels over time. Essentially, a learning instance can be regarded as the learning of one or more knowledge points (or knowledge components, Knowledge Component, KC). Essentially, a student's response to a question reflects to some extent the proficien...
