A control chart defines boundaries for a normal signal based on the statistics of the training set, which, in this case, refers to values from a correctly working system. During deployment, an alarm system is built to warn when the signal is exceeding the boundaries.
We will introduce and build a control chart based on the IoT data using the following steps:
In the first subsection, we will show you how to define and visualize a control chart.
A control chart defines the normal functioning of a process by a statistical range. We define this range by calculating the following statistics over the training window:
Once these boundaries have been set, we can visualize the control chart in a line plot. As an...
