An irrelevant variability normalization approach to discriminative training of multi-prototype based classifiers and its applications for online handwritten Chinese character recognition

作者:

Highlights:

• Jointly discriminative training of feature transforms and classifier parameters.

• Rprop optimization for SSM-MCE based objective function is adopted.

• Both piecewise linear transform and weighted sum of linear transforms are compared.

• The IVN-based recognizer can be made both compact and efficient by using fast-match.

• Experiments show the effectiveness of our approach over the state-of-the-art.
