Spatially-Distributed Interactive Behaviour Generation for Architecture-Scale Systems Based on Reinforcement Learning
Bibliographic record
Abstract
This thesis is part of the research activities of the Living Architecture System Group (LASG). LASG develops immersive, interactive art sculptures combining concepts of architecture, art, and electronics which allow occupants to interact with immersively. The primary goal of this research is to investigate the design of effective human-robot interaction behaviours using reinforcement learning. In this thesis, reinforcement learning is used adapt human designed behaviours to maximize occupant engagement. \n \nAlgorithms were tested in a simulation environment created using Unity. The system developed by LASG was simulated and simplified human visitor models are designed for the tests. Three adaptive behaviour modes and two exploration methods were compared in the simulated environment. We showed that reinforcement learning algorithms can learn to increase engagement by adapting to visitors' preferences and exploring with parameter noise performed better than action noise because of wider exploration. \n \nA field study was conducted based on the LASG's installation Aegis, Transforming Space exhibition at the Royal Ontario Museum (ROM) from June 2nd to October 8th, 2018. The experiment was conducted in a natural setting where no constraints are imposed on visitors and group interaction is accommodated. Experimental results demonstrated that learning on top of human designed pre-scripted behaviours (PLA) is better at increasing visitors engagement than only using pre-scripted behaviours (PB). Visitor responses to the GodSpeed standardized questionnaire suggested that PLA is more highly rated than PB in terms of Likeability and interactivity.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
