| Abstract: |
| The random forest decision tree is used to predict the probability distribution of the visual competition results of the WEB bounce visual flow interface, which provides a basis for determining the rationality of user visual flow on WEB interface and the user visual flow for optimizing the page layout. The main characteristics of the interface-bounce visual flow are discussed, and so the proposal that visual flow characteristics of the random jump of the WEB interactive interface are derived from its intrinsic visual competition mechanism is put forward. The conjectures for the competition influence factors is proposed and verified with a large number of control variables visual competition experiments, and the conclusion on the correlation between factors and visual competition results is obtained. For the varified impact factors, the experimental data is used to train the random forest algorithm, and the decision tree of the simulated competition process is constructed to carry out optimal experiment to actual cases. The constructed random forest decision tree can better simulate the visual competition mechanism of the bounce visual flow. Through the interface optimization experiment, it is verified that the method can significantly improve the user’s visual process. |
