Thanks Anoop, for the question. I too have the same doubt as yours. So to repeate, your question was: "With *either* option, all the constituent phrases of a target hypothesis come from a single table, but different hypothesis can use different tables. Each hypothesis is scored using one table only. I did not understand the* " additional options are collected from the other tables" *bit in the documentation. "
So, if each hypothesis is scored using a single table then why it is said that "additional options are collected from other tables". It sounds somewhat contradicting or maybe I am missing something. Please let us know if anybody knows what it mean. Thanks a lot. On Tue, Dec 22, 2015 at 4:52 AM, Anoop (അനൂപ്) <[email protected] > wrote: > Thanks for your inputs.
