We propose a model-based online reinforcement learning approach for continuous domains with deterministic transitions using a spatially adaptive sparse grid in the planning stage. The model learning employs Gaussian processes regression and allows a low sample complexity. The adaptive sparse grid is introduced to allow the representation of the value function in the planning stage in higher dimensional state spaces. This work gives numerical evidence that adaptive sparse grids are applicable in the case of reinforcement learning.
