Bootstrapped DQN is a reinforcement learning algorithm that improves exploration efficiency by using randomized value functions and bootstrapping techniques. The paper addresses the challenge of efficient exploration in reinforcement learning (RL), where agents must balance exploration (trying new actions) and exploitation (using known actions to maximize rewards). Traditional methods like ε-greedy are inefficient for deep exploration, requiring exponentially more data. Bootstrapped DQN leverages uncertainty estimates from deep neural networks to enable efficient and deep exploration, significantly improving learning speed and performance in complex environments. The algorithm uses a shared neural network architecture with multiple bootstrapped "heads" that independently learn value functions. Each head is trained on a subset of the data and provides a distribution over possible values, allowing the agent to explore more effectively. Bootstrapped DQN is computationally efficient and parallelizable, and it performs well in the Arcade Learning Environment (ALE), where it outperforms traditional methods like ε-greedy in most games. It achieves human-level performance in many games, often faster than DQN. The paper also discusses the importance of deep exploration in RL, where agents must plan over multiple time steps to learn effectively. Bootstrapped DQN enables this by approximating a distribution over Q-values using bootstrapping. This approach allows the agent to explore more efficiently and generalize better to new situations. The algorithm is tested on various environments, including stochastic MDPs and Atari games, where it demonstrates significant improvements in learning efficiency and performance. Bootstrapped DQN is compatible with complex nonlinear value functions and can be applied to a wide range of RL problems. It is computationally efficient and can be scaled to large systems. The paper also compares Bootstrapped DQN with other exploration strategies, showing that it outperforms them in terms of learning speed and cumulative rewards. The algorithm is implemented with a shared network architecture and multiple bootstrapped heads, allowing for efficient exploration and learning in complex environments.Bootstrapped DQN is a reinforcement learning algorithm that improves exploration efficiency by using randomized value functions and bootstrapping techniques.
