This workshop is a collaboration between John and artist Cian McLoughlin that explores the intersection of art, neuroscience, mathematics, and machine learning through the evolution of portraiture and face recognition.

It connects:

  • How artists try to capture the essence of a person,
  • How the brain recognises faces using the Fusiform Face Area (FFA),
  • How mathematics represents faces through dimensionality reduction,
  • How computers use Eigenfaces and machine learning to recognise and re-create faces.
  • The presentation culminates in the idea that only a few images are needed to form a mathematical “portrait”, an Eigenface, representing the essence of a person, not just their appearance.
