Embodiment Construction
[0086] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0087] A subspace clustering method based on the analysis of high-dimensional overlapping data, such as figure 1 As shown, the method of this embodiment is as follows.
[0088] Step 1: Input the data matrix X to be clustered.
[0089] Step 2: Establish a weighted mixed-norm subspace representation model for the data matrix X that needs to be clustered. The specific method is:
[0090] Step 2.1: Combining sparse subspace clustering (SSC) and least squares regression (LSR) algorithm ideas to establish l 1 The mixed norm subspace representation model of norm and Frobenius norm is shown in the following formula:
[0091]
[0092] Among them, ||·|| 1 for l 1 Norm, ||·|...
