We briefly highlight some interesting ... to incorporate such growing discounts, result- ing in perplexity improvements over modified Kneser-Ney and Jelinek-Mercer baselines. 1 Introduction Discounting, or subtracting from the count o...

... status of the morphemes of each type as a mass in terminology. So the transi- tions of Pf and Rf, with changing N, express the changes of the status of the morphemes of each type in the terminology. ... which is not of much interest. The more important and interesting is the actual transition of the mean frequencies within a realistic range of N, because the size...

A process of local ambiguity packing allows the parser to pack sub- parses that are rooted in the same non-terminal ... to the true parse of the sentence. The parser accommodates the skipping of words of the input string by allowing shift operations to be per- formed from inactive state nodes...
