维特比算法是一种动态规划算法用于寻找最有可能产生观测事件序列的-维特比路径-隐含状态序列,特别是在马尔可夫信息源上下文和隐马尔可夫模型中。术语“维特比路径”和“维特比算法”也被用于寻找观察结果最有可能解释相关的动态规划算法。例如在统计句法分析中动态规划算法可以被用于发现最可能的上下文无关的派生(解析)的字符串,有时被称为“维特比分析”。

We consider in this paper deploying external knowledge transfer inside a simple double agent Viterbi algorithm which is an algorithm firstly introduced by the author in his preprint "Hidden Markov Based Mathematical Model dedicated to Extract Ingredients from Recipe Text". The key challenge of this work lies in discovering the reason why our old model does have bad performances when it is confronted with estimating ingredient state for unknown words and see if deploying external knowledge transfer directly on calculating state matrix could be the solution instead of deploying it only on back propagating step.
