Qny is performed after 30 2 Designing of Dynamic Neural Networks the generation of each layer of neurons. Moreover, based on the defined evaluation criterion it is possible to make the selection of neurons in the layer: ⎧ (l) (l) Q1 (ˆ y1,1 ) . . Qny (ˆ y1,1 ) ⎪ ⎪ ⎪ (l) (l) ⎪ ⎪ Q1 (ˆ y1,2 ) . .

The next source of the structure errors can be caused by the selection methods applied during network synthesis. From the theoretical point of view, the selection method should ensure the choice of optimal structure of the network. Unfortunately, an unappropriate assumption of parameters influencing on the selection method can lead to the rejection of the neurons which should be included in the network. In order to prevent this situation the proposed in Sect. 1 the SSM should be applied during the GMDH network synthesis.
