What is Deep Reinforcement Learning Atari Games?
Deep Reinforcement Learning Atari Games applies deep neural networks to reinforcement learning algorithms for mastering Atari 2600 games from raw pixel inputs using benchmarks like the Arcade Learning Environment.
DQN by Mnih et al. (2013) first demonstrated learning control policies directly from high-dimensional sensory input with 5111 citations. The Arcade Learning Environment (ALE) by Bellemare et al. (2013) standardized evaluation across 100+ Atari games with 1024 citations. Successors like Bootstrapped DQN (Osband et al., 2016, 460 citations) and model-based RL (Kaiser et al., 2019, 420 citations) improved exploration and sample efficiency.
Why It Matters
Atari benchmarks validated deep RL for visual decision-making, enabling agent performance exceeding humans on most games (Mnih et al., 2013). ALE standardized testing for general AI agents across diverse dynamics (Bellemare et al., 2013). These advances underpin robotic control and real-time strategy games like StarCraft (Liu, 2019) and MOBA (Ye et al., 2020).
Key Research Challenges
Sample Inefficiency
Model-free methods like DQN require millions of environment interactions (Mnih et al., 2013). Model-based approaches reduce this but struggle with model accuracy in Atari (Kaiser et al., 2019). Over 10 million frames often needed for human-level play.
Exploration Deficiency
Epsilon-greedy exploration fails in sparse reward Atari games. Bootstrapped DQN uses randomized value functions for efficient exploration (Osband et al., 2016). Still lags behind model-based planning in rare event discovery.
Training Instability
Deep RL experiences deadly triad of unstable targets, bootstrapping, and function approximation (Mnih et al., 2013). Parallel methods scale training but introduce synchronization issues (Nair et al., 2015). Stability remains key barrier to generalization.
