Abstract

fetched live from OpenAlex

We present an algorithm for direct octree construction from range images. It uses a key property of most range sensors that all the voxels on sensed object surfaces are "visible" from the sensor. This enables us to define a projection map for range images. The projection map is used for efficiently checking if a given voxel is in the free region. Furthermore, this key property also reduces the number of faces to be checked for the nodes when constructing octrees. The algorithm is efficient in both memory space and run time, and is useful for sensor-based articulated robot motion planning, which is the main motivation for this work.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
