This paper presents a new kind of smoothing technique based on the mutual information for Bi-gram model. The model parameters, probabilities for bigram, are discounted or compensated according to the mutual information, whose rationality is indicated by minimizing the perplexity.
本文则针对二元模型,提出了一种基于互信息的平滑技术,其基本思想是根据模型中每个二元对的互信息的高低对其概率进行折扣或补偿,并用极小化困惑度原则体现了模型的合理性。
