Hi, I am trying to understand the multiple decoding paths feature in Moses.
The documentation (http://www.statmt.org/moses/?n=Advanced.Models#ntoc7) describes 3 methods: both, either and union The following is my understanding of the options. Please let me know if it is correct: - With *both* option, the constituent phrases of the target hypothesis come from both tables (since they are shared) and are scored with both the tables. - 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. - With *union* option, the constituent phrases of a target hypothesis come from different tables and are scored using scores from all the tables. Use 0 if the option doesn't appear in some table, unless the *default-average-others=true* option is used. Regards, Anoop. -- I claim to be a simple individual liable to err like any other fellow mortal. I own, however, that I have humility enough to confess my errors and to retrace my steps. http://flightsofthought.blogspot.com
