Research on data analysis of English intelligent assistant teaching system based on BP neural network algorithm

This study applies BP neural network to English teaching assistant system, confirms the parameters of BP neural network, then uses the students’ English test data of a university to train and test the system. The results show that the system can meet the error requirements when the parameters are fixed. Through the performance test of the test set data of the teaching aid system and comparison after the test, the results show that the error generated by the prediction results can meet the requirements of this kind of system.
