I hope everyone had a good 4th of July!
We’ll be meeting again this Thursday (7/11) at 5:30 PM in the Brochstein Pavilion. This week, we’re going to talk about the inscrutability of our current methods of artificial intelligence. One of the interesting things about the neural networks that are used in all forms of data analysis today is that they can’t be interpreted well (or at all). Computer scientists can train them to accurately determine whether a YouTube video has a cat in it, but how the cat is encoded in the network is a mystery even though we know the properties of every simulated neuron. This mystery might even be logically impossible to solve, raising some questions on the limits of being able to understand our own brains.
