Problems solved by technology

[0005] However, in terms of simulating the change of students' knowledge status in answering activities, both types of models have the following shortcomings: First, in terms of knowledge application, for the same exercise, different students use the knowledge points of each knowledge point according to their own knowledge status. The specific gravity is differen

Abstract

The invention relates to a knowledge tracking method and system based on a dynamic key value gating loop network. The method comprises the steps of obtaining a historical answer sequence of a studentin an interaction log data set; determining a knowledge point feature matrix and a knowledge state feature matrix according to the historical answer sequence; constructing a dynamic key value gating recurrent neural network according to the knowledge point feature matrix, the knowledge state feature matrix and the gating recurrent neural network; and carrying out knowledge tracking on the knowledge state of the student by utilizing the dynamic key value gated recurrent neural network. According to the knowledge tracking method and system based on the dynamic key value gating loop network, theaccuracy of knowledge tracking is improved.

Description

technical field [0001] The invention relates to the field of knowledge tracking, in particular to a knowledge tracking method and system based on a dynamic key-value gated loop network. Background technique [0002] With the rapid development of Internet education, there are a large number of learners on online learning platforms, which leads to many difficulties in the platform's evaluation of students' knowledge mastery status and personalized learning guidance. Knowledge tracking is a student learning status prediction model widely used by intelligent online learning platforms. According to students' historical answering sequence, knowledge tracking can model the interaction process between students and exercises, so as to track students' knowledge mastery status at each stage. There are two main categories in the field of knowledge tracking: traditional knowledge tracking models and deep knowledge tracking models. [0003] The traditional knowledge tracing model repres...
