3.2. Incremental neural network รุป
The INeN is a two-layer network. Fig. 2 shows the structure of the INeN. The nodes in the first
layer of the INeN are formed by the feature vectors. The number of nodes in the first layer is automatically determined by the learning algorithm. The winner-takes-all guarantees that there will be
only one node activated. Each output node represents a different information (mineral or a kind of crop). The labels of the output nodes are saved in the second layer, which is called the index layer.
