Path Planning using Neural A* Search
TL;DR: This work reformulates a canonical A* search algorithm to be differentiable and couple it with a convolutional encoder to form an end-to-end trainable neural network planner that outperformed state-of-the-art data-driven planners in terms of the search optimality and efficiency trade-off.
