【Python自然语言处理】隐马尔可夫模型中维特比（Viterbi）算法解决商务选择问题实战（附源码超详细必看）

需要源码请点赞关注收藏后评论区留言私信~~~一、统计分词统计分词基本逻辑是把每个词语看做由单字组成，利用统计学原理计算连接字在不同文本中出现的次数，以此判断相连字属于特定词语的概率。二、隐马尔可夫模型当一个随机过程在给定现在状态及所有过去状态情况下，其未来状态的条件概率分布仅依赖于当前状态，那么此随...

隐马尔可夫模型的Viterbi解码算法

前言前面在做自然语言处理时涉及到一些词性标注的工作，一般会使用隐马尔科夫模型（HMM）来实现词性标注，而HMM模型的解码实现算法一般就会使用Viterbi算法。关于穷举法 HMM模型有多种应用，这里说的是其中一个常见应用，即根据观察序列找到最可能的隐含状态序列。最朴素的想法就是直接穷举所有可能的...
