The proposed fuzzy ARTMAP variant is found to outperform fuzzy ARTMAP in a mapping task. Another novel self-organising architecture, loosely based upon a particular implementation of ART, is proposed here as an alternative to the fixed state-space decoder in a seminal implementation of reinforcement learning.

reinforcement learning problems. The standard Reinforcement Learning (RL) account provides a principled and com-prehensive means of optimising a scalar reward signal in a Markov Decision Process. However, the theory itself does not directly address the imperative issue of generali-sation which naturally arises as a consequence of large or. Reinforcement learning is a very common framework for learning sequential decision tasks. On the one hand, deep learning is of course the best set of algorithms we must learn to represent. So far, the combination of these two different models is the best answer, and we are very challenging in learning very good state representations.

A Self-Organising State Space Decoder for Reinforcement Learning Shaun Marriott and Robert F. Harrison Abstract A self-organising architecture, loosely based upon a particular implementation of adaptive resonance theory (ART) is used here as an alternative to the fixed decoder in the seminal implementation of reinforcement learning of Barto, Sutton and Anderson (BSA).

Marriott and R.F. Harrison. Sutton and Andrew G. Barto, in their Reinforcement Learning book (): Reinforcement Learning is best understood by stating the problem that we want to solve [5].

The problem is that of learning to achieve a goal solely from interaction with the environment. The decision maker or learning element of RL is called an agent.

In this work, a classical Reinforcement Learning (RL) model is used. Self-Organizing Maps SOM algorithm consists of a set of neurons usually arranged in a one or two- dimensional grid[2].

DeepMind trained an RL algorithm to play Atari, Mnih et al. 2 Reinforcement Learning In reinforcement learning problems, an agent interacts with an unknown environment.

At each time step, the agent observes the state, takes an action, and receives a reward. The goal of the agent is to learn a policy (i.e., a mapping File Size: KB.

Our experiment shows that such high dimensionality reinforcement learning problem can be solved in a short time with our approach.

While the learning framework is clear and there is virtually unlimited training data available, there are two main challenges: (a) The space of codes is very vast and the sizes astronomical; for instance a rate 1/2 code over information bits involves designing 2 codewords in a dimensional space.

Computationally efficient encoding and decoding procedures are a must, apart from high reliability .The SOM maps the input space in response to the real-valued state information, and a second SOM is used to represent the action space.

We use the Q-learning algorithm with a neighborhood update function, and an SOM for Q-function to avoid representing very large number of states or continuous action space in a large tabular : Chang-Hsian Uang, Jiun-Wei Liou, Cheng-Yuan Liou.Request PDF | Q Learning Based on Self-organizing Fuzzy Radial Basis Function Network | A fuzzy Q learning based on a self-organizing fuzzy radial basis function (FRBF) network is proposed to.
