Modelling of Machine-Aided Human Group Motion
Bibliographic record
Abstract
The ACANTO project is developing robotic assistants to aid the mobility and recovery of mobility-impaired and older adults. One key feature of the project's robotic assistants is aiding with navigation in chaotic environments. Prior work has solved this for a single user with a single robot, however for therapeutic outcomes ACANTO supports social groups and group activities. Thus these robotic assistants must be able to efficiently support groups of users walking together. This requires an efficient navigation solution that can handle large numbers of users, maintain (de-facto) group cohesion despite unpredictable behaviours, and operate rapidly on embedded devices. We address these challenges by: using sensor information to develop behavioural traces, clustering traces to determine groups, modeling the groups using the social force model, and finding an optimal navigation solution using statistical model checking. The new components of this solution are validated on the ETH Zurich dataset of pedestrians in an open environment.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
