摘要: |
利用谱降维方法可以归结为求解带权图Laplacican矩阵L(G)的特征值λn-t对应的特征向量这一理论,通过代数方法估计λn-t的下界,并讨论非带权图的情况下λn-t的下界. |

Eigenvalue Estimation in Dimensionality Reduction Theory |
|

Abstract: |
The application of spectral dimension reduction method can be attributed to solve the eigenvectors corresponding to the eigenvalues of weighted graph Laplacican matrix L(G).The lower bound of λn-t is given by using algebra method,and discussed the case of non-weighted graph. |
