Abstract

fetched live from OpenAlex

This paper presents a spatial-semantic modeling system featuring automated learning of object-place relations from an online annotated database, and the application of these relations to a variety of real-world tasks. The system is able to label novel scenes with place information, as we demonstrate on test scenes drawn from the same source as our training set. We have designed our system for future enhancement of a robot platform that performs state-of-the-art object recognition and creates object maps of realistic environments. In this context, we demonstrate the use of spatial-semantic information to perform clustering and place labeling of object maps obtained from real homes.This place information is fed back into the robot system to inform an object search planner about likely locations of a query object. As a whole, this system represents a new level in spatial reasoning and semantic understanding for a physical platform.

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.
