Testing meta-mapping (https://arxiv.org/abs/2005.04318) in simple grid-world RL tasks (with pixel inputs).
The color-dimension to shape-dimension meta-mapping generalization experiment code can be found in the more_distant_generalization branch (https://github.com/lampinen/homm_grids/tree/more_distant_generalization), but note that the analysis code for those experiments is in this branch.
