In order to improve the accuracy of cancer diagnosis
a model is proposed for cancer diagnosis
which based on the supervised Kohonen neural network.Adding an output layer on the basis of the Kohonen neural network
make the unsupervised neural network into supervised neural network-Sohonen which has the same network output number as the classification.The experimental results show that the supervised Kohonen neural network model is effective in clustering to the samples of the level of gene expression
so as to improve the accuracy and scientificity of cancer diagnosis
provide the certain reference value for the research on the treatment of cancer.
