Porphyrin sensor array system can detect lung cancer specific markers in exhaled gases
output vary from marker to marker. A pattern recognition algorithm based on backpropagation( BP) neural network and principal component analysis( PCA) is proposed and is applied in porphrin chemical sensor array integrated system. The sensitive points is selected by calculating principal component scores in porphyrin sensor array
and reserve value of each gas sensitive points
and template of recognition is formed as the input layer of the BP neural network to achieve the goal of removing redundant data. Comparing with the result of clustering analysis and BP neural network identification without reducing dimension and data after reducing dimension as input
the result of the proposed algorithm can identify precisely for lung cancer specific markers.
