LPP Locality Preserving Projections

LPP: Locality Preserving Projections % Note: After applying some simple algebra, the smallest eigenvalue problem: % data^T*L*data = \lemda data^T*D*data % is equivalent to the largest eigenvalue problem: % data^T*W*data = \beta data^T*D*data % where L=D-W; \lemda= 1 - \beta. % Thus, the smallest eigenvalue problem can be transformed to a largest % eigenvalue problem. Such tricks are adopted in this code for the % consideration of calculation precision of Matlab.

  • 还可以,可以用,这好需要LPP代码降维呢
  • 很有用啊 我是在这基础上运行的
  • 没用,下了一个降维的matlab工具包
  • 不是很实用,算法运行出现错误
