Two studies indicated a preference of a biologically-inspired selective memory over an absolute memory companion. Consequently, we present a preliminary implementation of a forgetting mechanism that enables the companion to create "generalised event representations" from its experiences allowing the companion to learn from past encounters.

Computational algorithms inspired by nature, such as PSO, have been successfully applied to a range of optimization problems. Our idea is to train a number of robots to interact with each other, attempting to simulate the way a collective of animals behave, as a single cognitive entity. What we have achieved is a swarm of robots that interacts like a swarm of insects, cooperating with each other accurately and efficiently. We describe the two different PSO topologies implemented, showing the results obtained, a comparative evaluation, and an explanation of the rationale behind the choices of topologies that enhanced the PSO algorithm.
