applying reinforcement learning methods to the simulated experiences just as if they had really happened. Typically, as in Dyna-Q, the same reinforcement learning method is used both for learning from real experience and for planning from simulated experience. The reinforcement learning method is thus the ÒÞnal common pathÓ for both learning

In this section, we present related work and background concepts such as reinforcement learning and multi-objective reinforcement learning. 2.1 Reinforcement Learning A reinforcement learning (Sutton and Barto, 1998) environment is typically formalized by means of a Markov decision process (MDP). An MDP can be described as follows. Let S fs 1 .

learning techniques, such as reinforcement learning, in an attempt to build a more general solution. In the next section, we review the theory of reinforcement learning, and the current efforts on its use in other cooperative multi-agent domains. 3. Reinforcement Learning Reinforcement learning is often characterized as the

Meta-reinforcement learning. Meta reinforcement learn-ing aims to solve a new reinforcement learning task by lever-aging the experience learned from a set of similar tasks. Currently, meta-reinforcement learning can be categorized into two different groups. The first group approaches (Duan et al. 2016; Wang et al. 2016; Mishra et al. 2018) use an

Reinforcement learning methods provide a framework that enables the design of learning policies for general networks. There have been two main lines of work on reinforcement learning methods: model-free reinforcement learning (e.g. Q-learning [4], policy gradient [5]) and model-based reinforce-ment learning (e.g., UCRL [6], PSRL [7]). In this .

Using a retaining wall as a case-study, the performance of two commonly used alternative reinforcement layouts (of which one is wrong) are studied and compared. Reinforcement Layout 1 had the main reinforcement (from the wall) bent towards the heel in the base slab. For Reinforcement Layout 2, the reinforcement was bent towards the toe.

Abstract. Reinforcement learning o ers one of the most general frame-work to take traditional robotics towards true autonomy and versatility. However, applying reinforcement learning to highdimensional movement systems like humanoid robots remains an unsolved problem.

of quantization on various aspects of reinforcement learning (e.g: training, deployment, etc) remains unexplored. Applying quantization to reinforcement learning is nontrivial and different from traditional neural network. In the context of policy inference, it may seem that, due to the sequential decision making nature of reinforcement learning,

Keywords Multi-agent learning systems Reinforcement learning. 1 Introduction Reinforcement learning (RL) is a learning technique that maps situations to actions so that an agent learns from the experience of interacting with its environment (Sutton and Barto, 1998; Kaelbling et al., 1996). Reinforcement learning has attracted attention and been .

In contrast to the centralized single agent reinforcement learning, during the multi-agent reinforcement learning, each agent can be trained using its own independent neural network. Such approach solves the problem of curse of dimensionality of action space when applying single agent reinforcement learning to multi-agent settings.

Reinforcement learning methods can also be easy to parallelize and generally provide greater flexibility to trade-off computation time and accuracy. 3.1 Q-learning Q-learning (Watkins and Dayan 1992) is the canonical 'model free' reinforcement learning method. Q-learning works on the 'state-action' value function Q : S 5

There have been some efforts in applying reinforcement learning to automated vehicles (6) (7) (8), however, in some of the applications the state space or action space are arbitrarily discretized to fit into the RL algorithms (e.g. Q-learning) without considering the specific characteristics of the studied cases.

In recent years, scientists have started applying reinforcement learning in Tetris as it displays e ective results in adapting to video game environments, exploit mechanisms and deliver extreme performances. Current thesis aims to introduce Memory Based Learning, a reinforcement learning algo-
