Chaotic SVM Prediction Model of High-rise Building Based on Multi-scale EMD Decomposition

A new idea was put forward for chaotic characteristics and time-variable law of surface subsidence of goaf by means of EMD and prediction methods of chaotic. Problems of space reconstruction of IMFS, establishment chaotic prediction model and application of model were discussed. EMD-SVM methods were used for modeling and predicting the goaf subsidence. The result of the simulation experiment shows that the new model have a high accuracy in prediction of the deformation sequence.
