我们提出了一个经典的光束阈值技术的变化,这是一个数量级的速度比传统的方法,在相同的性能水平。我们还提出了一种新的阈值技术,全球阈值,它结合了新的梁阈值,给出了一个额外的因素,两个改善,和一种新的技术,多通道解析,可以与其他人结合,产生又一个50%的改善。我们使用一种新的搜索算法,同时优化阈值参数的各种算法。
We present a variation on classic beam thresholding techniques that is up to an order of magnitude faster than the traditional method, at the same performance level. We also present a new thresholding technique, global thresholding, which, combined with the new beam thresholding, gives an additional factor of two improvement, and a novel technique, multiple pass parsing, that can be combined with the others to yield yet another 50% improvement. We use a new search algorithm to simultaneously optimize the thresholding parameters of the various algorithms.
