Nevertheless, since we use a uniform amount of training data for every language, and since varying γ would prevent us from improv- ing the efficiency of dynamic programming, as ex- plained in §4, in this ... there is no input text of an unknown language without learning data. In other words, we use supervised learning. In line with recent trends in unsupervised segmentation, the...
