....the current classification error (used as resource value) can be used to determine where to insert new RBF units. Third, the networks can generalize well and have a relatively small size. A performance comparisons of GNG with other neural network models have been made by M. Kunze [7] and F. Hamker [3]. 2 Double Growing Neural Gas 2.1 The Mechanism of DGNG The cell growing mechanism of DGNG is nearly the same as in GNG. The only difference is that in DGNG two new cells are inserted simultaneously instead of only one new cell as in GNG. In other words, in each insertion step of GNG only one ....

....is good enough. Second, since positioning of RBF units and supervised training of connection weights is performed in parallel, the current classification error can be used to determine where to insert new RBF units. Third, the networks can generalize well and have a relatively small size [11]. 3 Externally Growing Cell Structures (EGCS) 3.1 Resource Variable and Insertion Criterion We can use GCS with different means. It is essential that new cells are inserted in such a way that the expected value of a certain error measure or signal counter or resource value (the accumulated ....
