Abstract

The hidden Markov model (HMM), a powerful tool, has been widely applied to sequence analysis tasks such as speech recognition and handwriting recognition performance. However, its recognition performance is normally limited to the general framework. In this chapter, we investigate sophisticated techniques for improving its recognition performance. This includes a method for synthesizing string samples from isolated character images. Second, enhanced features are derived considering the uniqueness of Chinese characters and text line normalization is added to improve feature discrimination. Third, discriminative training based on MPE criteria is explored in the context of Chinese handwriting recognition for the first time. Fourth, a bridge is built between a segmentation-free and a segmentation-based system. This chapter also discusses the distributed training of the bigram language model.
