Table 2 Features description
Feature | Description | Window size | Time lag |
|---|---|---|---|
\(AOT_{Max}\) | Maximum \(AOT\) data in the time window | \(n_{1}\) | 1 |
\(AAV_{Max}\) | Maximum \(AAV\) data in the time window | \(n_{2}\) | 1 |
\(I_{Max}\) | Maximum \(I\) data in the time window | \(n_{3}\) | 1 |
\(IDLE\) | \(IDLE = 1\) if there is at least one day IoMT receives no data from the equipment in the time window. Otherwise, \(IDLE = 0\) | \(n_{4}\) | 1 |
\(AOT_{dMax}\) | \(AOT_{dMax} = 1\) If the maximum absolute value of \(AOT_{d}\) is greater than a threshold \(a\) in time window. Otherwise, \(AOT_{dMax} = 0\) | \(n_{5}\) | 1 |
\(AAV_{dMax}\) | \(AAV_{dMax} = 1\) If the maximum absolute value of \(AAV_{d}\) is greater than a threshold \(b\) in time window. Otherwise, \(AAV_{dMax} = 0\) | \(n_{6}\) | 1 |
\(I_{dMax}\) | \(I_{dMax} = 1\) If the maximum absolute value of \(I_{d}\) is greater than a threshold \(c\) in time window. Otherwise, \(I_{dMax} = 0\) | \(n_{7}\) | 1 |
\(Arcing_{w}\) | \(Arcing_{w} = 1\) if there is at least one day IoMT receives the observation of arcs in the tube from the equipment in the time window. Otherwise, \(Arcing_{w} = 0\) | \(n_{8}\) | 1 |
