Building fast and compact convolutional neural networks for offline handwritten Chinese character recognition

作者:

Highlights:

• We propose a new method for building fast and compact CNN model for large scale handwritten Chinese character recognition (HCCR).

• We propose a new technique, namely Adaptive Drop-weight (ADW), for effectively pruning CNN parameters.

• We proposed the Global Supervised Low Rank Expansions (GSLRE) method for accelerating CNN model.

• Comparing with the state-of-the-art CNN method for HCCR, our approach is about 30-times faster yet 10-times smaller.
