Reinforcement learning with soft state aggregation math analysis present a new approach based on bayes theorem. State abstractions for lifelong reinforcement learning. Rather than state lookup table for computing q value problem definition and summary of notation we consider the problem of solving large markovian decision processes mdps using rl algorithms and compact function approximation. Reinforcement learning with soft state aggregation nips. Modelbased reinforcement learning with state aggregation.
Pdf reinforcement learning rl depends on constructing a lookup table for the. Reinforcement learning rl depends on constructing a lookup table for the value function of state action pairs. Reinforcement learning with soft state aggregation. Corollary 1 implies corollary 2 because tdo is a special case of qiearning. Pdf effective experiences collection and state aggregation in. Pdf reinforcement learning generalization using state. State oftheart adaptation, learning, and optimization 12. It is widely accepted that the use of more compact representations than lookup tables is crucial to scaling reinforcement learning rl algorithms to realworld. One of the simplest and most popular approaches is state ag gregation. Consequently, when learning in environments with largescale state action space, rl fails to achieve practical convergence rates.
