Robot Swarm Behavior Suggests Forgetting May Be Important To Cultural Evolution

Hallie Siegel writes: Can we learn about human cultural evolution by studying how group behaviour in robots evolves? Researchers in the Artificial Culture Project are trying to do just that. Prof. Alan Winfield from the Bristol Robotics Lab discusses his latest research on modelling the process by which cultural memes develop in robots when they pass learned behaviours to other robots in their group. Some interesting findings suggest imitation noise (ie. when the behaviour isn't learned perfectly) and forgetfulness (i.e. when the robot has only limited memory of the behaviours it is trying to imitate) lead to stronger cultural memes in the robot behaviour.
