Embodiment Construction
[0010] The present invention will be further introduced below in conjunction with the accompanying drawings and embodiments. The method of the present invention is divided into three major steps.
[0011] The first step: data set collection and transformation,
[0012] First process the collected data set, digitize the non-numerical data set, grayscale the image data set, and then use the dimensionality reduction algorithm to reduce its dimensionality for subsequent processing. Secondly, matrix the collected data set, for example, x∈R 1×N Converting it into a matrix sample is where d 1 × d 2 =N.
[0013] Step 2: Model training
[0014] 1) First construct the regularization term R BC
[0015] Assume that the matrix pattern of the binary classification is and the class of each pattern is Use the clustering method to cluster each category separately, and calculate its cluster center as in equation (1):
[0016]
[0017] where the number of clusters of each class...
