According to the theoretical analysis and practical results of the experiments, besides the value-consistency which is never supported by existing approaches, the proposed model also performs very well in the three key factors for evaluating an approach to dimensionality reduction (i.e. reduction rate, reconstruction error, and complexity): (1) strong ability in dimensionality reduction and feature preservation鈥攖he reduction rate reaches as high as circa 280-420, and the average reconstruction error is circa 1-5%; (2) linear time complexity鈥攊t is applicable to most huge datasets.
