[Retracted] Evaluation of Students’ Online Learning Behavior and Perception of Psychological State Based on Data Mining

Algorithm 1

Prediction of psychological state perception.
Input: basic information data, OLB data, symptom self-rating scale data, classification or regression algorithm.
Output: psychological state perception model
(1)Extract static feature vector S from basic information data;
(2)Construct label vector from symptom self-rating scale data;
(3)Connect the static feature vector S, the dynamic feature vector D, and the label vector Y into a data matrix, which is divided into a training data set Train and a test data set Test according to the data division method.
(4)Train the training data set as the input of the classification or regression algorithm to get the final classification or regression model.
