A novel training approach based on the back-propagation algorithm is introduced. In the proposed approach, initially, a set of training vectors is obtained by applying the Karhunen-Loe've transform on the training patterns. The training is first started in the direction of the major eigenvectors of the correlation matrix of the training patterns and then continues by gradually including the remaining components, in their order of significance. With this approach, the number of computations is significantly reduced and the learning rate is improved. The performance of this method is compared with the standard back-propagation algorithm in segmenting a synthetic noisy image
