| Abstract: |
| The problem of norm non-negative matrix factorization with L2,1 is studied based on kernel technique in image clustering. By kernel-based sparse robust non-negative matrix factorization method, the sparseness and robustness of the algorithm are obtained, and the clustering performance is improved. This method can also be extended to the application of text clustering. |
