Close-class-set discrimination method for large-class-set pattern recognition using support vector machines
Chigurupalli Chandra Sekhar, Kazuya Takeda, Fumitada Itakura · 2003
In conventional approaches for multi-class pattern recognition using support vector machines, learning involves discrimination of each class against all the other classes. In the close-class-set discrimination method, learning involves discrimination of each class against a subset of classes confusable with it. The effectiveness of the proposed method is demonstrated for 80-class consonant-vowel recognition.
