Abstract
We consider the view planning problem where the sensor, a range scanner, is mounted on a robot mechanism with non-trivial geometry and kinematics. The robot+sensor system is required to explore the environment (obstacle/free space). We present a novel information theoretical approach in which the sensing action is viewed as reducing ignorance of the planning space, the C-space of the robot. The concept of C-space entropy is introduced as a measure of this ignorance. The next view in the planning process is determined by maximizing the expected reduction of C-space entropy, called maximal entropy reduction (MER) criterion. A computational tool to implement MER is the notion of information gain density function. Experimental results with a real PUMA robot with a wrist-mounted range scanner and a simulated robot show the effectiveness of the MER criterion in efficient exploration of environments for motion planning problems.

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 it
