Addi- tionally, instead of maximising scores in each beam cell, we sum the inside scores for each derivation that produces a given string ... Each graph node repre- sents a hypothesis translation substring covering a sub-span of the source string. The space of trans- lation sub-strings is exponential in each cell’s span, and our...
