Advances in Artificial Intelligence

The Economist reports on the latest versions of learning-driven, artificially intelligent algorithms: https://www.economist.com/science-and-technology/2018/08/30/a-sense-of-curiosity-is-helpful-for-artificial-intelligence

Summary: First-gen curiosity-driven AI was curious in the sense that it was designed to seek out observations/interactions that it couldn't predict (motivated by prediction error). The latest generation of these algorithms instead seeks out those problems that have a steep learning curve - In other words, they are motivated by the rate of prediction error change. This solves the problem of less productive exploration that first generation curiosity-driven AI ran into.
