... backward computations are carried out explicitly, and the for- ward pass is done through sampling, i.e. we traverse the machine only computing forward probabilities for arcs leaving the sampled state. 4 Once ... likely pronunciation for each word. It is straightforward to extend to multiple pronunciations by first sampling a pronunciation for each word and then sampling a segmentatio...

... Translation, a considerable ef- fort has also been made to include deeper linguis- tic information in automatic evaluation metrics, both syntactic and semantic (see Section 2 for de- tails). However, ... accuracy measure for the reliability of very low/high metric scores, it is nec- essary to define quality thresholds for both the human assessments and metric scales. Defining thresholds...

... Therefore we suggest to use HMTM and tree-modified Viterbi algorithm for tasks interpretable as label- ing nodes of dependency trees. In par- ticular, we show that the transfer phase in a Machine ... specialized t-node’s attributes). Another motivation for using t-trees is that we believe that local tree contexts in t-trees carry more information relevant for correct lexical choice, co...
