“…In general, training network for motion planning requires a massive dataset, since a trajectory is generated by a sequence of control inputs. Therefore, many previous neural network approaches exploit successful trajectories by traditional motion planners to create training datasets [19]- [21], [23], [24]. However, all data samples are not equally important for the training of neural networks [26], [27].…”

“…3) Criticality Test: Local primitives may or may not create "challenging regions," and finding if a configuration belongs to such a region is not straightforward. For example, the authors of [34] chose regions with maximum path density while [35] and [6] identified "challenging regions" using graph properties of a roadmap. To overcome this problem, we introduce training via a criticality test, which associates key configurations from solution paths to relevant local primitives.…”

“…State-of-the-art motion planning algorithms such as PRM [17] and RRT [23] use random sampling of low-level configurations to compute a path from the robot's current location 𝐵1 to its target location 𝐾. Such sampling-based methods fail to efficiently sample configurations from confined spaces such as doorways and corridors under uniform sampling [29].…”
