Level of Confidence is a face-recognition camera that has been trained with the faces of the 43 disappeared students from Ayotzinapa School in Iguala, Mexico. As a viewer stands in front of the camera, the system uses algorithms to find which student’s facial features look most like the viewer’s and gives a percent-based “level of confidence” on the accuracy of the match. Because the students were likely murdered, the piece will always fail to make a positive match, but the commemorative aspect of the project reminds us of both the relentless search for the missing and how their identities and fate could so easily overlap with our own. Rafael Lozano-Hemmer (Mexico, b. 1967) is an internationally exhibiting electronic and performance artist who divides his time between Madrid and Montreal.
