Time series analysis is a statistical technique used to analyze and interpret sequential data points collected over time. This method of data analysis provides insights into the underlying patterns, trends, and behaviors of a given dataset with a different perspective than other statistical analyses. ...
vehicle time series data analysis 以HADOOP为代表的云计算提供的仅仅是一个算法执行环境,为大数据的并行计算提供了在现有软硬件水平下最好的(近似)方法。并不能解决大数据应用中的全部问题。从详细应用而言,通过物联网方式接入IT圈的数据供应商(Data Provider)所面临的首要问题是数据分析的算法。其次才是算法的并行计...
A time series database (TSDB) is a database optimized for time-stamped or time series data. Time series data are simply measurements or events that are tracked, monitored, downsampled, and aggregated over time. This could be server metrics, application performance monitoring, network data, ...
