“Twin Mirror exposes the hidden biases in machine learning technologies that will allow the smart buildings and cities of the future to sense and gather data about their inhabitants and urban contexts. A live video feed of the exhibit’s visitors is processed by two different face-recognition models trained on two different sets of data to reveal the “digital twin” – an imperfect interpretation of the visitor’s image produced by the technology. A third large LED screen projects this data back into the urban context in real-time. Twin Mirror was exhibited at the 2017 Seoul Biennale of Architecture and Urbanism.”
