The core layer of SOFM neural network is（ ）.
答案:competition layerIn order to divide the input patterns into several classes, the distance between input pattern vectors should be measured according to the similarity. （ ）are usually used.
答案:Euclidean distance method and cosine method
SOFM neural networks are different from other artificial neural networks in that they adopt competitive learning rather than backward propagation error correction learning method similar to gradient descent, and in a sense, they use neighborhood functions to preserve topological properties of input space. （ ）
答案:对
For SOFM neural network, the competitive transfer function (CTF) response is 0 for the winning neurons, and 1 for other neurons.（ ）
答案:错
When the input pattern to the network does not belong to any pattern in the network training samples, SOFM neural network can only classify it into the closest mode. （ ）
答案:对
