    1. For one test, the researchers trained the neural network with data from an unidentified mobile phone service that detailed 43,606 subscribers’ interactions over 14 weeks. This data included each interaction’s date, time, duration, type (call or text), the pseudonyms of the involved parties and who initiated the communication.

      Graph of Phone Calls/Texts

      One of the tests involved the researcher creating a directed graph of user calls/texts including timestamp, type of interaction (call versus text), and duration. Just based on the pattern of interaction, the AI could be fed the graph of a known individual and be spotted in the anonymized dataset about 15% of the time. Adding the second derivative interactions into the search graph increased the positive result to just over 50%.
