Pd. Gader et Ma. Khabou, AUTOMATIC FEATURE GENERATION FOR HANDWRITTEN DIGIT RECOGNITION, IEEE transactions on pattern analysis and machine intelligence, 18(12), 1996, pp. 1256-1261
An automatic feature generation method for handwritten digit recogniti
on is described. Two different evaluation measures, orthogonality and
information, are used to guide the search for features. The features a
re used in a backpropagation trained neural network. Classification ra
tes compare favorably with results published in a survey of high-perfo
rmance handwritten digit recognition systems. This classifier is combi
ned with several other high performance classifiers. Recognition rates
of around 98% are obtained using two classifiers on a test set with 1
,000 digits per class.
