Analysis of the information transmission path of national sports culture based on gradient descent algorithm in the era of informationization

Abstract

Abstract The digitization inheritance of national sports culture is an inevitable requirement of the new era, so studying its communication characteristics in the digital age is necessary. In this paper, the cognitive semantics of its cultural imagery is obtained based on the analysis of the connotation of national sports culture, and the informational imagery is extracted based on the cultural semantic analysis. The fast gradient descent algorithm optimizes the sampling and dissemination process of information during establishing the SIRI communication network for cultural imagery. Changes in the state and popularity of the dissemination nodes were explored by changing the external social environment and the input of the information carrier. When the probability of social environment increases from 0.15 to 0.95, the node with state S transforms into an information dissemination node faster and finally tends to a stable value of 0. In terms of information carriers, the degree of the flow of video dissemination will be graded higher than other carriers, and the popularity of video dissemination is 2.45%, 3.14%, and 5.21% higher than audio, image, and text, respectively, when the dissemination reaches the 4th generation. The information dissemination model optimized using a gradient descent algorithm can accurately capture the dissemination characteristics of national sports culture, thus proposing a better information transmission path.
