Abstract

fetched live from OpenAlex

The general context of this work is the guidance of an autonomous mobile robot directly from the information contained in a sequence of images. Because of the complexity of the problem to be solved, the authors decided first to concentrate on the implementation of a behaviour of lower level rather than route planning or environment exploration: the avoidance of obstacles. This article deals with the identification of image regions corresponding to the navigable free space. It presents a method of obstacle detection based on preliminary determination of the parts of the image corresponding to the ground over which the vehicle moves.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
