Written by: Akbar Karimi Reviewed by: Michal Aibin Graph Traversal 1. Overview In this tutorial, we’ll go over the definition of the Beam Search algorithm, explain how it works, and zoom in on the role of the beam size in the algorithm. 2. How Does Beam Search Work? Beam Search...
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...
第二步的时候,我们已经选择出了in、jane、September作为第一个单词的三个最可能选择,beam search针对每个第一个单词考虑第二个单词的概率,例如针对单词“in”,我们将 y^{<1>} ='in',然后将它喂给 x^{<2>} ,输出结果 y^{<2>} 作为第二个单词的概率输出。因为我们关注的是最有可能的 P(y^{<2>},y...
Beam search algorithm is widely used in AI field. To k-size beam search, due to only k paths is maintained the key to optimize the accuracy of beam search is how to select the k paths. In most of search algorithms, the k candidates with the most high pe...

Wiki定义:Incomputer science,beam searchis aheuristicsearch algorithmthat explores a graph by expanding the most promising node in a limited set. Beam search is an optimization ofbest-first searchthat reduces its memory requirements. Best-first search is a graph search which orders all partial solut...
