Grouping method of data processing (GMDH) the multilayered algorithm (MIA) was achieved through the use of genetic algorithm selection procedures, the algorithm get less errors generated optimal neuron cloning operation. The procedure was selected based on the probability of fitness, as well as some of the network input that from existing neurons parent looking for new neurons. Essentially cloning the optimal neurons clones parameters slightly adjusted. Experimental results show that genetically modified by cloning operation the GMDH network performance is superior other methods that elected from the machine learning library.
