What is the difference between time series and data streams?

Aaron Brown is right on target. A data stream is any flow of information. A time series is a data set in which order and time are fundamental elements that are central to the meaning of the data. read more

So a data stream can have time series data or non time series data. If it has time series data, it will usually be analyzed by real time techniques that differ from standard time series techniques for stored data. read more

As this chapter focuses on the mining of stream data, time-series data, and sequence data, let’s look at each of these areas. Imagine a satellite-mounted remote sensor that is constantly generating data. The dataaremassive(e.g.,terabytesinvolume),temporallyordered,fastchanging,andpoten-tially infinite. This is an example of stream data. read more

Real-time detection and classification of signals or events present in time series data is a fairly common need. Stereotypical examples include identifying high-risk conditions in ICU data streams or classifying signals present in acoustic data from diagnostic or monitoring sensors. read more
