Policy Gradient Reinforcement Learning with Keras. it reflects a model-free reinforcement learning algorithm. the average reward is a direct representation of the episode length.


Reinforcement learning [Sutton and Barto1998] has recently shown many impressive results. It has achieved human-level performance in a wide variety of tasks, including playing Atari games from raw pixels [Guo et al. 2014, Mnih et al. 2015, Schulman et al. 2015], playing the game of go [Silver et al. 2016] and robotic manipulation [Levine et al. 2016, Lillicrap et al. 2015].

But unlike multi-level architectures in hierarchical reinforcement learning that are mainly used to decompose the task into subtasks, PRR employs a multi-level architecture to represent the experience in multiple granular- ities. from Sutton Barto book: Introduction to Reinforcement Learning Part 4 of the Blue Print: Improved Algorithm. We have said that Policy Based RL have high variance. However there are several algorithms that can help reduce this variance, some of which are REINFORCE with Baseline and Actor Critic.

Its underlying idea, states Russel, is that intelligence is an emergent property of the interaction between an agent and its environment.

12 Oct 2020 Most existing research work focuses on designing policy and learning algorithms of the recommender agent but seldom cares about the state 

For this example, create actor and critic representations for an agent that can be trained against the cart-pole environment described in Train AC Agent to Balance Cart-Pole System. One of the main challenges in offline and off-policy reinforcement learning is to cope with the distribution shift that arises from the mismatch between the target policy and the data collection policy. In this paper, we focus on a model-based approach, particularly on learning the representation for a robust model of the 6.

Comparison of the convergence of the RL algorithm with fixed policy parameterization (30-knot spline) versus evolving policy parameterization (from 4- to 30-knot spline). In this paper, we demonstrate the first decoupling of representation learning from reinforcement learning that performs as well as or better than end-to-end RL. We update the encoder weights using only UL and train a control policy independently, on the (compressed) latent images. Deploy the trained policy representation using, for example, generated C/C++ or CUDA code. At this point, the policy is a standalone decision-making system. Training an agent using reinforcement learning is an iterative process.

Model-free algorithms cache action values, making them cheap but inflexible: a candidate mechanism for adaptive and maladaptive habits. Representations for Stable Off-Policy Reinforcement Learning popular representation learning algorithms, including proto- value functions, generally lead to representations that are not stable, despite their appealing approximation characteristics. As special cases of a more general framework, we study two classes of stable representations.

For value-based learning, representation model and a good decision-making model [11,12]. Over the past 30 years, reinforcement learning (RL) has become the most basic way for achieving autonomous decision-making capabilities in artificial systems [13,14,15].
