I’ve been invited to give a talk next week at the Gatsby Unit in London. Gatsby is known around the world for its research into theoretical neuroscience, computational neuroscience and machine learning. It’s home to famous researchers such as Peter Dayan, David MacKay and, until recently, Geoffrey Hinton. I’ll also get to [...]
