Methods and apparatus to determine when a smart device is out-of-tab

A non-transitory computer readable storage medium comprising instructions which, when executed cause one or more processors to at least:

• identify a first smart television that corresponds to a first panelist by comparing first data from the first smart television to second data from the first panelist;
• generate training data by labelling the first smart television as in-tab or out-of-tab based on the second data from the first panelist;
• and
• train a model using the training data to determine a tab status for a second smart television.

A method to determine a status of a smart television, the method comprising:

• identifying, by executing an instruction with a processor, a first smart television that corresponds to a first panelist by comparing first data from the first smart television to second data from the first panelist;
• generating, by executing an instruction with the processor, training data by labelling the first smart television as in-tab or out-of-tab based on the second data from the first panelist;
• and
• training, by executing an instruction with the processor, a model using the training data to determine a tab status for a second smart television.
