提出的正交LPP具有的优良特性是：能够较好的重构数据，并包含较好的判别能力-The orthogonal locality

preserving projection (OLPP) method produces orthogonal basis functions

and can have more locality preserving power than LPP. Since the locality

preserving power is potentially related to the discriminating power, the

OLPP is expected to have more discriminating power than LPP
