Abstract

fetched live from OpenAlex

In this paper, we present a visually-guided mobile robot that is capable of executing a task requiring complex human-robot interaction (HRI). The robot delivers verbal messages among the inhabitants of an office-like environment. Essential to the robot's robust performance is our behavior-based robot control architecture enhanced with a state of the art decision theoretic planner that takes into account the temporal characteristics of the robot's actions. The decision theoretic layer is based on the partially observable Markov decision process (POMDP) framework allowing us to achieve principled coordination of complex subtasks implemented as robot behaviors/skills. We compute approximate POMDP policies using the randomized point-based value iteration algorithm and we present heuristics for improving its computational efficiency.

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.
