In text-related tasks, the observation sequence is given, so we don't need to care the probability of the observation, but the state sequence induced.
在与网络文本相关的信息抽取任务中,观察值序列都是给定的,所以不需要考虑得到观察值的概率,而只需要关注观察值引起的状态转移的概率。
Here, the HMM is employed to produce a best speech state sequence which is warped to a fixed dimension vector and the RBF neural network is used as classifier.
该方法首先利用HMM生成最佳语音状态序列,然后用函数逼近技术产生对最佳状态序列进行时间规正,最后通过RBF神经网络进行分类识别。
By using the high order differential state sequence, the casuality of the system and the capability of resistance to identity deception and differential attacks is enhanced.
使用高阶差分状态序列,增强了系统因果强度,加强了抵抗身份欺骗和差分分析攻击的能力。
