Autonomous underwater vehicle control using reinforcement learning policy search methods

Autonomous underwater vehicles (AUV) represent a challenging control problem with complex, noisy, dynamics. Nowadays, not only the continuous scientific advances in underwater robotics but the increasing number of subsea missions and its complexity ask for an automatization of submarine processes. This paper proposes a high-level control system for solving the action selection problem of an autonomous robot. The system is characterized by the use of reinforcement learning direct policy search methods (RLDPS) for learning the internal state/action mapping of some behaviors. We demonstrate its feasibility with simulated experiments using the model of our underwater robot URIS in a target following task

Towards Direct Policy Search Reinforcement Learning for Robot Control

This paper proposes a high-level reinforcement learning (RL) control system for solving the action selection problem of an autonomous robot. Although the dominant approach, when using RL, has been to apply value function based algorithms, the system here detailed is characterized by the use of direct policy search methods. Rather than approximating a value function, these methodologies approximate a policy using an independent function approximator with its own parameters, trying to maximize the future expected reward. The policy based algorithm presented in this paper is used for learning the internal state/action mapping of a behavior. In this preliminary work, we demonstrate its feasibility with simulated experiments using the underwater robot GARBI in a target reaching task

The International Student Experience at the University of Southampton

This video highlights aspects of the lives of international students at UG, PGT and PGR levels from all 3 faculties. It shows them responding to a range of authentic scenarios about the experiences and challenges of being an international student at the University of Southampton in the early 21st century from their perspective. The overall objective of this short film therefore is to capture experiences and viewpoints of international students currently at the University. By viewing this video, it is hoped that staff will be able to gain a better understanding and appreciation of what their international students are feeling and facing at various points along their student life cycle.

A Day in the Life of a Student (2006)

This is self playing Powerpoint with sound, which was made by researchers in Learning Technology, in 2001, suggesting what the life of a student in 2006 might look like. It is interesting to see how far we have come (or not come) in the time since.
