| Abstract(in English) | A new type of feature transformation technique that extends locality preserving projection (LPP) is proposed and successfully applied to age classification using facial images. We call this technique "class-distance weighted locality preserving projections (CDLPP)". CDLPP performs coordinate transformation using distances between classes as weights while LPP performs coordinate transformation using information on nearby geometric distances between data. In the proposed method, transformation matrices are trained so as to preserve nearby class data structures by weighting the data of nearby classes. An age classification test shows the effectiveness of the proposed method : it reduced the errors of conventional methods such as PCA, LDA, and LPP. |
