VAST 2015 Mini-Challenge 1

Synthetic dataset from the VAST 2015 Mini-Challenge 1. This tensor represents events (‘check-in’, ‘movement’) of attendees at a theme park over one weekend. Hidden within the data are various malicious events. Non-zero values are binary, indicating that an attendee performed an event. The modes are time-person-action-xloc-yloc, with time at the resolution of seconds. The order-3 tensor is the same data with location information removed.
