nearest neighbor approximation meaning in Chinese

On the other side , we use nearest neighbor approximation to calculate gussian mixture densities , which can reduce recognition time by 6 . 67 % compared with standard viterbi beam search algorithm
另一方面，使用高斯混合概率密度的最近邻快速估算方法，使标准viterbibeam搜索算法的搜索速度提高了6 . 67 。
Further more , we improve the nearest neighbor approximation method by calculat e mixtures ordered by likelihood of being the best scoring mixture . the likelihood is calculating from previously processed data . this improved method can reduce recognition time by 15 . 56 % compared with standard viterbi beam search algorithm
本文对最近邻快速估算方法进行改进，在搜索过程中根据已处理过的数据统计出各个高斯混合分量产生最高对数概率的概率，并依此预测随后的计算中最有可能产生最高对数概率的高斯混合分量，优先计算更有可能产生最高对数概率的高斯混合分量，使标准viterbibeam搜索算法的搜索速度提高了15 . 56 。
