Abstract :
An artificial neural network is applied to nondestructive inspections using thermal imager. The use of an artificial neural network is presented for classifying test data as corresponding to bonded and disbonded regions in sample materials. The backpropagation learning for a multi-layer feedforward neural network is applied to this classification. The trust region method is adopted to the backpropagation learning problem. Results of numerical tests are summarized.
