| Abstract: |
| In this paper,we investigate the structure identification of a given complex network.By noticing the sparse structure of the network,we propose an l1-regularized output least squares model.Simulations show that the whole algorithm is very efficient for larger networks with or without noise. |
| Key words: complex network structure identification l1 regularization iteratively rewei ghted least squares Newton method |
