Time Series Analysis with Machine Learning
Workflow: Time_Series This workflow shows an example of time series analysis using some of the pre-packaged components in "00_Components/TimeSeries" on the EXAMPLES server..After reading the time series of the number of visitor to a web site, we want to predict next day's number of visitors given thenumber of visitors in the past N=7 days.Here we use the Linear Regression, but any other numerical prediction algorithm would have worked as well.
