Research on Practice Evaluation System of Higher Vocational Preschool Education Based on Artificial Intelligence

To improve the quality of practical teaching and promote the synchronization of practical teaching and practice, the theory of artificial intelligence network is introduced into the evaluation of practical teaching quality, and the relevant mathematical model is established. Firstly, a perfect practical teaching evaluation index system is provided, and the related index system and quality standard are established. Then, when the convergence speed of BP algorithm training network is slow, genetic algorithm is used to optimize the operation parameters of the network, the optimization results are taken as the initial value of BP algorithm, and BP algorithm is used to train the network until the required accuracy is reached. Finally, by using data cleaning, network training and rationalization test, a more reasonable result is obtained, which provides a new idea for teaching quality evaluation.
