Abstract
The metaverse is a virtual world that exists entirely in a computer-generated environment, and it offers a new frontier for machine learning. One of the major challenges for using machine learning in the metaverse is MLOps (Machine Learning Operations), an emerging field that focuses on deploying and managing machine learning models in production. It has been widely acknowledged that machine learning models require a large amount of data to learn and make accurate predictions, and such data is generated progressively in real-time as human users interact with the metaverse. Due to the human-centric nature of the metaverse, it goes without saying that, once deployed, models need to be able to adapt to the constantly changing interactive environment and still make accurate predictions. Borrowing a page from software engineering, in this paper, we explore the design space of human-centric continuous integration in metaverse environments, where labeled data samples accumulated with explicit human interactive behavior (e.g., using virtual reality or augmented reality headsets) are used for fine-tuning a deployed deep learning model over a sustained period of time. We propose SPIN, a new mechanism that efficiently utilizes data samples collected from a large number of participating human users over time to fine-tune a deployed model that is shared across all the users. In an extensive array of experimental results using image classification and state-of-the-art <monospace xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">YOLOv8</monospace> object detection models as case studies, we show that SPIN outperforms FedBuff, a state-of-the-art asynchronous FL mechanism from conventional federated learning, by a substantial margin.

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.
