TTAGaze: Self-Supervised Test-Time Adaptation for Personalized Gaze Estimation
Bibliographic record
Abstract
In this paper, we address the problem of personalized gaze estimation. Due to the anatomical differences between individuals, current personalized gaze models often rely on fine-tuning or fully-supervised methods with labeled calibration samples, which may not be practical in real-world applications. To tackle this limitation, we propose an approach called Self-Supervised Test-Time Adaptation for Personalized Gaze Estimation (TTAGaze), which enables adaptation with small unlabeled data at test time. Our goal is to develop a gaze estimation model specifically adapted to a target person using only a few unlabeled images. We call this setting as unsupervised few-shot personalized adaptation in gaze estimation, which is more aligned with real-world scenarios compared to existing approaches. Additionally, Our approach leverages self-supervised learning and meta-learning. The model consists of the main task (gaze estimation) and a self-supervised auxiliary task. During training, the two task are trained using a coupled method. At test time, adaptation is achieved by optimizing the self-supervised loss adapted to an unseen person with a few unlabeled data. The model parameters are learned via model-agnostic meta-learning (MAML) to facilitate effective unsupervised few-shot personalized adaptation in gaze estimation. Experimental results demonstrate that the proposed method outperforms alternative approaches on several widely-used benchmark datasets.

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.
