Deep reinforcement learning (deep RL) | EBSCO

Deep reinforcement learning (deep RL) is an advanced approach to training artificial intelligence (AI) that merges reinforcement learning with deep learning techniques. In reinforcement learning, AI systems learn to make decisions by exploring different actions within an environment, gradually refining their strategies based on rewards received for achieving specific goals. Deep RL enhances this process by incorporating deep neural networks with multiple layers, enabling the AI to efficiently analyze vast datasets and recognize complex patterns. This method has led to significant breakthroughs in various domains, particularly in games where deep RL algorithms, such as AlphaGo, have outperformed top human players in complex board games and video games. While deep RL offers promising capabilities, it also raises concerns about job displacement and ethical implications, as its increasing efficiency could lead to significant changes in the workforce. Proponents believe that, if developed responsibly, AI could enhance human productivity and open new avenues for scientific advancement, potentially leading to a more automated and efficient society. Overall, deep RL represents a significant evolution in AI, combining the strengths of learning from both large datasets and strategic decision-making.

Sim-to-Real Transfer of Robotic Control with Dynamics Randomization

Simulations are attractive environments for training agents as they provide an abundant source of data and alleviate certain safety concerns during the training process. But the behaviours developed by agents in simulation are often specific to the characteristics of the simulator. Due to modeling error, strategies that are successful in simulation may not transfer to their real world counterparts. In this paper, we demonstrate a simple method to bridge this "reality gap". By randomizing the dynamics of the simulator during training, we are able to develop policies that are capable of adapting to very different dynamics, including ones that differ significantly from the dynamics on which the policies were trained. This adaptivity enables the policies to generalize to the dynamics of the real world without any training on the physical system. Our approach is demonstrated on an object pushing task using a robotic arm. Despite being trained exclusively in simulation, our policies are able to maintain a similar level of performance when deployed on a real robot, reliably moving an object to a desired location from random initial configurations. We explore the impact of various design decisions and show that the resulting policies are robust to significant calibration error.

Structure in Deep Reinforcement Learning: A Survey and Open Problems

Reinforcement Learning (RL), bolstered by the expressive capabilities of Deep Neural Networks (DNNs) for function approximation, has demonstrated considerable success in numerous applications. However, its practicality in addressing various real-world scenarios, characterized by diverse and unpredictable dynamics, noisy signals, and large state and action spaces, remains limited. This limitation stems from poor data efficiency, limited generalization capabilities, a lack of safety guarantees, and the absence of interpretability, among other factors. To overcome these challenges and improve performance across these crucial metrics, one promising avenue is to incorporate additional structural information about the problem into the RL learning process. Various sub-fields of RL have proposed methods for incorporating such inductive biases. We amalgamate these diverse methodologies under a unified framework, shedding light on the role of structure in the learning problem, and classify these methods into distinct patterns of incorporating structure. By leveraging this comprehensive framework, we provide valuable insights into the challenges of structured RL and lay the groundwork for a design pattern perspective on RL research. This novel perspective paves the way for future advancements and aids in developing more effective and efficient RL algorithms that can potentially handle real-world scenarios better.
