Construction of Online Learning Evaluation System based on Principal Component Analysis Method

Abstract

With the continuous development of computers, colleges and universities need to attach importance to the combination of student teaching and computer-aided design. The teaching of parametric design is used to scientifically divide different teaching contents to help students meet the needs of the digital era. Use online resources to transfer offline teaching content to online to increase offline design analysis and discussion time. Therefore, how to improve the informatization level of university education management has become one of the important challenges that Chinese education departments are facing and must solve at this stage. For computer-aided design online courses is conducive to improving the quality of online teaching of such courses. Based on the implementation process and effect analysis of computer-aided design online course teaching, the formative multiple evaluation index of course effect is proposed. Based on the potential information of multimedia, a large number of researchers have begun to conduct data mining research on it and accumulated a large amount of data. The ROF-LGB model, a comprehensive classification model based on rotating forest and LightGBM, attempts to deeply explore the potential information of the actual teaching management data set. In this process, some thoughts on educational information management are put forward for readers' reference.
