Locally linear embedding is an efficient manifold learning approach. A modified locally linear embedding algorithm is proposed to cope with the interferences of affine transformations in handwritten digit recognition. In order to offset all kinds of affine transformations, the Euclidean distance is replaced by the tangent distance which is more appropriate for handwritten digit recognition based on image. And the number of neighborhood is computed automatically based on the similarity of images. Experimental results show that the accuracy rate of is improved.
