The Design Of Assessment System For Network Learning Based On Levenberg-Marquardt Algorithm

With the development of computer technology and the advance of the internet technology, e-learning gradually carries out in the field of education with a bang. The evaluation of e-learning plays a vital role in the entire e-learning. It not only needs to screen and select students, but also gives the students a feedback, corrects their behaviors and promotes the development of the students, so as to promote the development of the entire e-learning. Therefore, a scientific and effective e-learning evaluation system is crucial for e-learning.In this paper, I investigated and analyzed the research status of e-learning at our country and abroad. I found that the evaluation of e-learning is weak in the scientific designs of evaluation models, the scientific designs of evaluation contents and the scientific designs of evaluation standards in our country at present. On this basis, I compared the current evaluation methods of e-learning, and finally chose the LMBP neural network evaluation method of algorithm to design the evaluation system of e-learning.According to the concrete platform, I analyzed the deficiencies of its evaluation methods and the reasons why these deficiencies happened. On this basis, I redesigned the evaluation index system and the evaluation model. I used data mining to obtain data that can affect the effect of e-learning, and then I carried on data processing and sampling. After that, I wrote the program codes, trained the model and began the simulation test. The simulation results showed that after training the LMBP network model, it can approximate the objective function well. This showed that the e-learning evaluation model based on LMBP algorithm has a good generalization performance, and we can use a trained network assessment model to give reasonable evaluations to the online learners in this platform. At the end, the article analyzed the deficiencies in the design of the evaluation index system, and put forward the improvement plan.
