Designing Sparse Representations for Efficient Planning in Uncertain Environments
… of many regions are unknown prior to planning. If we reason about the uncertainty in the environment instead of assuming that all unknown space is free to move through, we can generate policies that result in, on average, more efficient navigation. However, designing models that enable …
