A perceptual image prediction model of professional dress style based on PSO-BP neural network.

In order to understand consumers' cognition of clothing style and design clothing products more in line with people's emotional needs, a garment style perceptual image prediction model based on PSO-BP neural network was constructed by taking professional dress as an example. Firstly, the professional dress samples were screened and the style design elements were deconstructed and coded. The Kansei engineering theory and factor analysis method were used to determine the representative adjectives, so as to reduce the cognitive dimension of the target users for the style characteristics and perceptual image of the dress. Then, using the sample style design element code as the input layer and the user's perceptual image evaluation score as the output layer, the PSO-BP neural network's perceptual image prediction model for professional dress styles is constructed. Finally, the sample data were input into the PSO-BP model, BP neural network and GA-BP model for simulation and calculation, and the error analysis of the results proved that the PSO-BP prediction model is effective and advanced. Designers can use this model to quickly transform customers' perceptual needs with dress style design elements, so as to improve the scientificity of design decision-making and better meet customer needs.
