本系列介绍几种序列对齐方法,包括Dynamic time warping (DTW),Smith–Waterman algorithm,Cross-recurrence plot Dynamic time warping (DTW) is a well-known technique to find an optimal alignment between two given (time-dependent) sequences under certain restrictions. ——Mei…
A recurrence plot (RP) is a straightforward way to visualize characteristics of similar system states attained at different times (Eckmann et al., 1987). ,即RP可识别在时间上伸缩的状态对.Cross-Recurrent Plot,形成一个二维坐标轴,坐标系里的黑色代表相似的状态对,实际上在这个坐标系里,大部分的点都不是黑色的.在对角线上的路…

这学期有<语音信号处理>这门课,快考试了,所以也要了解了解相关的知识点.呵呵,平时没怎么听课,现在只能抱佛脚了.顺便也总结总结,好让自己的知识架构清晰点,也和大家分享下.下面总结的是第一个知识点:DTW.因为花的时间不多,所以可能会有不少说的不妥的地方,还望大家指正.谢谢. Dynamic Time Warping(DTW)诞生有一定的历史了(日本学者Itakura提出),它出现的目的也比较单纯,是一种衡量两个长度不同的时间序列的相似度的方法.应用也比较广,主要是在模板匹配中,比如说用在孤立词…
DTW为(Dynamic Time Warping,动态时间归准)的简称.应用很广,主要是在模板匹配中,比如说用在孤立词语音识别,计算机视觉中的行为识别,信息检索等中.可能大家学过这些类似的课程都看到过这个算法,公式也有几个,但是很抽象,当时看懂了但不久就会忘记,因为没有具体的实例来加深印象. 这次主要是用语音识别课程老师上课的一个题目来理解DTW算法. 首先还是介绍下DTW的思想:假设现在有一个标准的参考模板R,是一个M维的向量,即R={R(1),R(2),……,R(m),……,R(M)},每…
让子弹飞一会 UVM框架,将验证平台和激励分开,env以下属于平台部分,test和sequence属于激励,这样各司其职.我们可以将sequence_item 比喻成子弹,sequencer 类比成弹夹,UVM平台就是个枪.如图所示uvm_sequence 的类继承关系. The sequence item is written by extending the uvm_sequence_item, uvm_sequence_item inherits from the uvm_object v…
