Even simple phones can tell if they are looking at a face or at least a photo of a face, and that is thanks to developments in teaching AI how to understand the makeup of a human face. This technology however originated in labs as researchers tried to use the enormous data processing capabilities of AI to understand how humans see faces. In this episode, we talk with Nikolaus Kriegeskorte about how his labs use AI to study the many different ways we see images. We also learn about how AI competition works, many AI can be made to do a task but we need to test and understand which is better to make better machines and programs in the future.
