To eliminate the impact on the original data, the visual design sample set is subjected to mathematical transformation in this paper. The Gini coefficient is calculated based on an attribute, the decision tree is trained, and a set of functions is taken to obtain the final output by averaging all decision trees to obtain an unbiased data set estimate and help construct the decision tree. The data analysis resulted in a significant increase in the overall indicators, with the imagery concept visual elements increasing from 60% to 100%, and the overall indicators were above 50%. More visual elements with traditional Chinese cultural meanings should be created in visual design practice and made to become a new carrier for the inheritance and regeneration of non-heritage traditional culture in visual design development.
