Dy. Tsai et al., BREAST-TUMOR CLASSIFICATION BY NEURAL NETWORKS FED WITH SEQUENTIAL-DEPENDENCE FACTORS TO THE INPUT LAYER, IEICE transactions on information and systems, E76D(8), 1993, pp. 956-962
We applied an artificial neural network approach to identify possible
tumors into benign and malignant ones in mammograms. A sequential-depe
ndence technique, which calculates the degree of redundancy or pattern
ing in a sequence, was employed to extract image features from mammogr
aphic images. The extracted vectors were then used as input to the net
work. Our preliminary results show that the neural network can correct
ly classify benign and malignant tumors at an average rate of 85%. Thi
s accuracy rate indicates that the neural network approach with the pr
oposed feature-extraction technique has potential utility in the compu
ter-aided diagnosis of breast cancer.
