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.

6 Annotations per Image on Average

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].

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.

66.78% Original Label Agreement
80.52% HLV Samples

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.

Feature Human Soft-Labels Synthetic Labels
Calibration
  • Improved on HLV samples
  • Lower KLD, Brier scores
  • Often harms uncertainty ranking
  • Fails to align with human uncertainty
Robustness
  • More stable convergence
  • Better generalization on difficult cases
  • Propagates synthetic biases
  • Struggles with human visual intuition
Uncertainty Alignment
  • Mirrors human uncertainty
  • Strong Spearman correlation
  • Negligible correlation with human uncertainty
33% of Mukhoti Labels Shifted After Human Re-annotation

A substantial portion of labels in the Mukhoti synthetic dataset changed when re-annotated by humans, highlighting the discrepancy between model-generated labels and human perception, and emphasizing the need for human-centric evaluation.
