On the Method of Choosing the Type About Interchange Based on Projection Pursuit Cluster Model

On the basis of building the index system interchange type, the paper puts forward a new method of Projection Pursuit Cluster Model from the angle of statistics. By means of Genetic Algorithm, the paper describes the key steps of Projection Pursuit Cluster Model with an example, and points out that the method is more objective when applied in the decision-making system which contains aboundant data and legible properties.
