heuristic function

In translation searching process , many ebmt systems can only rely on a heuristic guidance which is given by human . therefore that process will not be objective and always lean much on the intuition of system developer and may be overfitting to a special domain
但是,由于在ebmt系统进行译文搜索的过程中往往只能依靠人为设定的启发式函数进行指导,对人为因素的依赖较大,很容易造成对某个限定领域特点的过度拟合。
