Abstract Reinforcement Learning (RL) is a popular solution to train autonomous agents to solve tasks in environments with unknown dynamics. Despite the recent successes of RL in solving increasingly challenging tasks, it suffers from an excessive requirement of samples of interactions with the environment in order to learn a good solution. When applied to Multiagent Systems (MAS), RL allows to train agents to solve tasks while coordinating with other agents. However, the sample complexity of MAS solutions is even higher, and hence Multiagent RL is dependent on additional techniques to be applicable to complex tasks. We here rely on Transfer Learning methods to accelerate Multiagent RL through knowledge reuse. In the main Ph.D. project we proposed a framework in which agents reuse knowledge both from previously learned tasks and advice from other agents. The main purpose of this exchange project is to develop methods to reuse previous task solutions in order to later integrate them in theafore mentioned framework. Recently, the use of Curriculum Learning in Single-Agent RL achieved interesting benefits for the learning process, accelerating the learning process of complex tasks. We here intend to contribute Curriculum Learning algorithms specialized to Multiagent RL. This is a resubmission of process 2017/13729-0, approved by FAPESP but not realized because of the long time required for issuing a US visa. (AU) | |
