Calibration, Personalization, and Multimodal Adaptation
Calibration
In brief — site editorial, not from the paper
Adjusts the model's confidence so its stated probabilities match how often it is actually right, leaving its accuracy unchanged.
Definition
Calibration post-hoc aligns a model's output confidence scores with its empirical accuracy, correcting the systematic overconfidence or underconfidence produced by standard training objectives that optimize for discriminative accuracy rather than probabilistic faithfulness [73, 158]. Calibration does not improve the model's task accuracy, it improves the correspondence between the model's stated confidence and its actual accuracy (Reliability). From a system engineering and safety validation perspective, calibration operates not merely as a performance optimization, but as a critical operational safety constraint. Systems integrated into automated pipelines must mathematically bound their uncertainty; uncalibrated confidence scores inherently invalidate downstream threshold-based decision logic and fail-safe routing, mandating rigorous statistical auditing of calibration metrics.
