It is important to note the distinction between time series and sequential data. In both cases, the data consist of a sequence, or list of values, in which the order is important. Time series is a subclass of sequential data where the longitudinal co…

主讲人 张巍 (新浪微博: @张巍_ISCAS) 软件所-张巍<zh3f@qq.com> 19:01:27 我们开始吧,十三章是关于序列数据,现实中很多数据是有前后关系的,例如语音或者DNA序列,例子就不多举了,对于这类数据我们很自然会想到用马尔科夫链来建模: 例如直接假设观测数据之间服从一阶马尔科夫链,这个假设显然太简单了,因为很多数据时明显有高阶相关性的,一个解决方法是用高阶马尔科夫链建模: 但这样并不能完全解决问题 :1.高阶马尔科夫模型参数太多:2.数据间的相关性仍然受阶数限制.一个好…

在使用xampp进行开发的时候,我们都知道它只能支持一个PHP版本不能像PHPstudy那样方便进行不同版本的切换操作.因此我们手动的对于xampp进行改造一下,使其支持其他PHP版本 1. 从官网上下载指定的PHP版本 实例: 我本地是使用的PHP5.6版本,由于新项目开发,需要PHP7.3版本,因此我就直接找到对应的PHP版本即可(注意:线程与非线程和架构版本) 2. 修改相关配置文件 1)将下载并解压的PHP新版本放置在与之前PHP同一个目录之下 例如: 我之前的PHP路径 E:\xamp…
