An Assessment of Human vs. Model Uncertainty in Soft-Label Learning and Calibration
This study highlights that human-elicited soft-labels significantly improve model calibration and robustness by better capturing human uncertainty, especially for difficult samples. Synthetic labels, while easily fit, fail to align with human intuition. The research provides a controlled testbed for aligning human-AI uncertainty.

Human soft-labels capture nuanced uncertainty, leading to better model calibration and robustness, especially for ambiguous data. This aligns model uncertainty with human perception, a critical step for human-aligned AI.
Our study utilized an average of 6 high-quality annotations per image, demonstrating that significant calibration gains can be achieved with fewer annotations than previously thought, contrary to the 50-annotation standard [37].
Human Soft-Label Annotation Process
Case Study: Mukhoti Dataset Re-annotation
Our re-annotation of the Mukhoti dataset revealed a significant label mode shift for ~33% of samples. Models trained on original synthetic labels performed poorly when evaluated against human re-annotations, showing a ~28% accuracy drop. In contrast, models trained on human soft-labels achieved ~7% higher accuracy, demonstrating their superior alignment with human visual perception and a critical need for human-grounded evaluation over synthetic alternatives.
Synthetic labels, while easy to fit, often propagate biases and fail to capture human-level uncertainty. Human-centric soft-labels provide a more robust signal, leading to models that mirror human uncertainty throughout the learning process.
