... clusters are used for predicted and conditional words. In particular, for clustering conditional words, we try to minimize the perplexity of training data for a bigram of the form P(wi|Wi-1), ... clusters for words in different positions. For the predicted word, wi, we will denote the cluster of the word by PWi, and we will refer to this as the predictive cluster. . For the words ... been observed, however, in the performance of the different techniques for constructing clusters. In this study, we focused our research on novel techniques for using clusters – the ACM, in...
