Embodiment Construction
[0012] The present invention will be further introduced below in conjunction with accompanying drawing and embodiment: the method of the present invention is divided into three modules altogether.
[0013] Part I: Data Acquisition
[0014] This module includes two steps. First, the data is digitized; second, a Universum sample is generated.
[0015] 1) Digitize the image problem in reality: generate a matrix-represented data set for subsequent modules to process. The matrix data generated after acquisition can be further processed by classical methods for dimensionality reduction. A matrix sample is denoted as A, and each element of the matrix corresponds to a pixel conversion value of the sample, that is, the dimension d=m×n of the sample.
[0016] 2) Use the In-Between method to generate Universum samples: Universum samples are defined as samples that are in the same domain value range as the problem data set but do not belong to any category. For example, in the letter m...
