Compact MQDF classifiers using sparse coding for handwritten Chinese character recognition

作者:

Highlights:

• We use sparse coding to compact the parameters of MQDF classifier.

• An analysis is given to indicate that using the sparse representation to build compact MQDF classifier is feasible and valid.

• We learn multiple dictionaries rather than single dictionary to reduce the computational complexity.

• A weight-based assignment strategy is proposed to further alleviate the degradation of recognition accuracy.

• Experiments demonstrate the validation of the proposed methods.
