| Abstract [eng] |
In this paper we discuss the visualization of multidimensional vectors. A well-known procedure for mapping data from a high-dimensional space onto a lower-dimensional one is Sammon's mapping. This algorithm preserves as well as possible all inter-pattern distances. We investigate an unsupervised backpropagation algorithm to train a multilayer feed-forward neural netwok (SAMANN) to perform the Sammon's nonlinear projection and propose a parallel algorithm for SAMANN network. |
