It is recommended that the data be, normalized between slightly offset values such as 0.1, and 0.9 rather than between 0 and 1 to avoid, saturation of the sigmoid function leading to slow or, no learning (Hassoun, 1995; Masters, 1994). Determining UCS values in laboratory is costly and time consuming, hence, its indirect determination through use of rock index tests is of a great interest and advantage. Artificial Neural Networks: an overview and their use in the analysis of the AMPHORA-3 dataset. (4). The feedforward weights are used to select the, long-term memory for the networks. A bird's eye review of the various types of ANNs and the related learning rules is presented, with special emphasis on backpropagation (BP) ANNs theory and design. ASCE 5, 115–. fortunately, this campaign achieved its planned goal, and by the early 1970s many ANN researchers, There is an argument, however, as to whether, ANNs are distinctly different from statistical regres-, sion or whether they are extensions of these old, techniques (Cheng and Titterington, 1994). each with a new set of randomly initialized weights. Many others view, ANN regression is performed adaptively using non-, linear learning laws, whereas it is performed by, matrix inversion in statistical regression. Using the Integral Method and adopting the Entrainment Restriction Approach, the system of the equations of momentum and mass conservation of tracer was solved, extracting the axial velocity and concentration distributions. Η μέση ροή και η μεταφορά μάζας σε μία τέτοια φλέβα περιγράφονται από την ολοκλήρωση των εξισώσεων συνέχειας, ορμής και διάχυσης.
