Adaptation in Statistical Pattern Recognition Using Tangent Vectors.

Daniel Keysers, Wolfgang Macherey, Hermann Ney, Jörg Dahmen

Abstract: We integrate the tangent method into a statistical framework for classification analytically and practically. The resulting consistent framework for adaptation allows us to efficiently estimate the tangent vectors representing the variability. The framework improves classification results on two real-world pattern recognition tasks from the domains handwritten character recognition and automatic speech recognition.
