Research on the Application of Intangible Cultural Heritage Communication Based on BP Neural Network

In order to understand the current situation of the dissemination of intangible cultural heritage in Northeast Sichuan, this paper makes a descriptive statistical analysis of the current situation of the dissemination of intangible cultural heritage in Northeast Sichuan through interviews and questionnaires. Based on the index system of intangible cultural heritage dissemination in Northeast Sichuan, this paper constructs a BP neural network evaluation model to analyze the dissemination of intangible cultural heritage in Northeast Sichuan in the past five years. The results show that the current situation of the dissemination of intangible cultural heritage in Northeast Sichuan is “general”, and the model has high prediction accuracy. Finally, from the perspective of education mode, collaborative tourism, regional development and publicity activities, the paper puts forward the idea of collaborative development strategy of intangible cultural heritage, in order to provide reference for the protection of intangible cultural heritage in China.
