Robust locality preserving projections using angle‐based adaptive weight method
Locality preserving projections (LPP) method is a classical manifold learning method for dimensionality reduction. However, LPP is sensitive to outliers since squared L2‐norm may exaggerate the distance of outliers. Besides, the normalisation constraint of LPP may impair its robustness during embedd...
