This report presents the implementation and evaluation of a Deep Q-Network (DQN) agent for playing the Atari game Space Invaders. The agent was trained from scratch using Double DQN with experience replay and target network stabilization. After 2 million training steps, the agent achieved an average score of [X] on the Space Invaders environment, demonstrating competitive performance compared to baseline methods. This report details the algorithm selection, implementation details, experimental results, and analysis of the agent's performance.

The agent was trained for 2 million steps on an NVIDIA RTX 4060 GPU. Key observations:
\begin{itemize}
\item \textbf{Initial Phase} (0-100K steps): Random exploration, average score around 10-15
\item \textbf{Learning Phase} (100K-500K steps): Gradual improvement, score increases to 30-50
\item \textbf{Convergence Phase} (500K-2M steps): Performance stabilizes around 100-200
\item \textbf{Initial Phase} (0-100K steps): Random exploration with warmup, average score around 10-15
\item \textbf{Learning Phase} (100K-600K steps): Gradual improvement, score increases to 15-19

\section{Conclusion}
This project successfully implemented a DQN agent for playing Space Invaders from raw pixel inputs. The agent achieved an average score of [X], demonstrating competitive performance compared to baseline methods. The implementation highlights the effectiveness of deep reinforcement learning for Atari games and provides a solid foundation for exploring more advanced algorithms.
This project successfully implemented a DQN agent for playing Space Invaders from raw pixel inputs. The agent achieved an average score of 21.50 at the best checkpoint (1.8M steps), demonstrating competitive performance compared to random agents ($\sim$5). The implementation highlights the effectiveness of deep reinforcement learning for Atari games and provides a solid foundation for exploring more advanced algorithms.
The DQN algorithm, while relatively simple, remains a powerful approach for discrete action space problems. The key innovations of experience replay and target networks are crucial for stable training. Future work could explore more advanced variants like Rainbow DQN to further improve performance.
The DQN algorithm, while relatively simple, remains a powerful approach for discrete action space problems. The key innovations of experience replay and target networks are crucial for stable training. The use of Double DQN helped reduce overestimation bias, though some performance fluctuation was observed during training. Future work could explore more advanced variants like Rainbow DQN, Prioritized Experience Replay, or Dueling DQN architecture to further improve performance and training stability.
