The x axis corresponds to the cumulative time for processing the test set; for (a) and (c), the y axis corresponds ... al- gorithm using a small value for the stack size and then use it as initial point, both for the LK algo- rithm and for further Beam-Search optimization (where as before we v...

... Transforming the entire for- est to n-ary form is intractable, however, because the number of hyperedges would be exponential in n. Instead, we include only the top k n-ary back- traces for each forest ... Collapsing Binarization To facilitate a change in binarization, we transform the translation forest into n-ary form. In the n-ary forest, each hyperedge corresponds to an original gramm...
