A new method is presented which provides prediction of the spatially variant point spread function for the restoration of astronomical images, distorted by atmospheric turbulence when viewed using ground-based telescopes. Our approach uses reservoir computing to firstly learn the spatio-temporal evolution of aberrations caused by turbulence, and secondly,(More)
To facilitate further research in emergent turn-taking, we propose a metric for evaluating the extent to which agents take turns using a shared resource. Our measure reports a turn-taking value for a particular time and a particular time scale, or ‘resolution,’ in a way that matches intuition. We describe how to evaluate the results of simulations where(More)
A new technique for locating and tracking locations is presented. Optical data collected during motion is used to match the current surroundings with a point on a previously recorded “optical map” of locations. Sensing hardware and location algorithms are covered and the results from real-world street navigation are presented.
We describe a class of stateful games, which we call ‘medium-access games’, as a model for human and machine communication and demonstrate how to use the Nash equilibria of those games as played by pairs of agents with stationary policies to predict turn-taking behaviour in Q-learning agents based on the agents’ reward function. We identify which fixed(More)
