In general, the Beam Search Algorithm is not complete. This is illustrated in Trace 1 above. Even though the memory was not depleted, the algorithm failed to find the goal because it could not add any nodes to theBEAM. Thus, even given unlimited time and memory, it is possible for the ...
传统的广度优先策略能够找到最优的路径,但是在搜索空间非常大的情况下,内存占用是指数级增长,很容易造成内存溢出,因此提出了beam search的算法。 beam search尝试在广度优先基础上进行进行搜索空间的优化(类似于剪枝)达到减少内存消耗的目的。 Beam Search算法 新的概念 为了达到搜索的目的,beam search 引入了启发函数的...
Relatedly, beam search can get stuck at local optima. The algorithm may find itself in a state where any local change makes the solution worse, and only a relatively long series of steps will make it better. If each intermediate step looks bad to our heuristic evaluation function, then beam...

A novel multiple sub-tree and frame-synchronous beam search speech recognition algorithm is proposed and studied in this paper. The algorithm requires less execution time and memory usage, and keeps high recognition accuracy. Key word spotting models and bigram language models are included in the se...

This algorithm is effective in the suppression of many types of jammers. The number of noise samples M required in the construction of the adapted weight vector is approximately equal to L. In the special case of L narrowband noise jammers, for example, a choice of M = L usually reduces ...
