Neural Encodings for Energy-Efficient Motion Planning
Bibliographic record
Abstract
Neural motion planners can increase motion planning quality and, by reducing collision detection computations, improve runtime. However, when profiled on an accelerator-rich hardware system, neural planning contributes to more than 50% of the runtime, and 33% of the computation energy consumption, motivating the design of compute- and energy-efficient neural planners. In this work, we propose a neural planner using Binary Encoded Labels (BEL), where a set of binary classifiers are used instead of a typical regression network. Compared to conventional regression-based neural planners, the proposed BEL neural planner reduces neural planning (inference) computation and collision detection checks while maintaining equal or higher motion planning success rate across various motion planning benchmarks. This computation reduction can improve the computation energy efficiency of neural planning by <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1.4 \times-21.4 \times$</tex>. Finally, we demonstrate the trade-offs between collision detection and neural planning computation to maximize energy efficiency for different hardware configurations.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
