LTSA seeks to minimise a cost function that minimises the distances between points in the low-dimensional space and the tangent space. As shown in [16], the solution to this minimisation problem is formed by the d smallest eigenvectors of an alignment matrix F. The alignment matrix is found by iteratively summing over all local information matrices ... [Pg.19]
