8. This algorithm is used for dimension reduction. Input: a set of vectors {Xn є }, and dimension d,d<D. Output: a set of vectors {Yn є }

9. This Iterative algorithm is used for grouping of vectors. Input: a set of vectors {Xn є D}, number of groups-P. Output: a set of vectors {Xn є D}, which are labeled by (1…P).

10. This Iterative algorithm offers a statistical model for a set of vectors. Input: a set of vectors {Xn є D}, number of groups-P, expectations of each group, empiric probability, empiric variances. Output: a set of vectors {Xn є D}, which are labeled by (1…P).
