title = "Network Calibration by Temperature Scaling based on the Predicted Confidence",
abstract = "Calibrating neural networks is crucial in applications where the decision making depends on the predicted probabilities. Modern neural networks can be poorly calibrated. They tend to overestimate probabilities when compared to the expected accuracy. This results in a misleading reliability that corrupts our decision policy. We show that the magnitude of calibration error depends on the predicted confidence for each sample. This prediction confidence calibration paradigm is then applied to the concept of temperature scaling. We describe an optimization method that finds the suitable temperature scaling for each bin of a discretized value of prediction confidence. We report extensive experiments on a variety of image datasets and network architectures. Our approach achieves state-of-the-art calibration with a guarantee that the classification accuracy is not altered.",
