What can we learn from image compression about the genetic encoding of brain wiring?

May 15, 2021

You can describe a digital image by describing the coordinate and color of every individual pixel, meaning each of the smallest component ‘dots’ that together make up the picture.  Since pictures taken with modern cell phones and cameras have an ever increasing resolution, this leads to rather large image files to save and send to friends.  Fortunately, most images can…

Didn’t DeepMind just produce a self-learning AI?

April 15, 2021

Yes, they did.  MuZero was published just before Christmas 2020, and is arguably the most advanced artificial neural network based on reinforcement learning out there right now.  Its predecessor, AlphaZero already had the ability to teach itself both chess and Go (another two-person zero-sum-game without random elements).  AlphaZero beat world champions, but needed one important bit of information to learn:…

Is Artificial Intelligence today where brain research was 100 years ago?

April 1, 2021

Babies are not born with randomly connected brains and turned on to learn.  And yet, 100 years ago, neurobiologists were not so sure.  In fact, most of them rather liked the idea, because they disliked the alternative: the development of intelligent brains without learning – as if embryo development could determine who you are.  100 years ago, neurobiologists had only…
