Call Features
We employ features from RAPIDS-Call that cover the statistics of incoming/outgoing calls' duration (count, sum, mean, std, max, min, entropy), and the count of missed calls.
| Feature Name | Unit | Description |
count |
calls | Number of calls of a particular call_type (incoming/outgoing) occurred during a particular time_segment. |
distinctcontacts |
contacts | Number of distinct contacts that are associated with a particular call_type for a particular time_segment. |
meanduration |
seconds | The mean duration of all calls of a particular call_type during a particular time_segment. |
sumduration |
seconds | The sum of the duration of all calls of a particular call_type during a particular time_segment. |
minduration |
seconds | The duration of the shortest call of a particular call_type during a particular time_segment. |
maxduration |
seconds | The duration of the longest call of a particular call_type during a particular time_segment. |
stdduration |
seconds | The standard deviation of the duration of all the calls of a particular call_type during a particular time_segment. |
modeduration |
seconds | The mode of the duration of all the calls of a particular call_type during a particular time_segment. |
entropyduration |
nats | The estimate of the Shannon entropy for the the duration of all the calls of a particular call_type during a particular time_segment. |
timefirstcall |
minutes | The time in minutes between 12:00am (midnight) and the first call of call_type. |
timelastcall |
minutes | The time in minutes between 12:00am (midnight) and the last call of call_type. |
countmostfrequentcontact |
calls | The number of calls of a particular call_type during a particular time_segment of the most frequent contact throughout the monitored period. |
