Enhancing Deep Neural Network Reliability with Refinement and Calibration
A new paper proposes methods to enhance the reliability of deep neural networks (DNNs) by focusing on calibration and refinement. The authors introduce a novel loss function and a unified training framework called RefCal, which jointly optimizes calibration, refinement, and accuracy. Their approach significantly outperforms existing methods in terms of accuracy and refinement metrics.
- ▪Deep neural networks often provide unreliable confidence estimates, which can undermine user trust.
- ▪The proposed RefCal framework improves DNN reliability by optimizing calibration, refinement, and accuracy simultaneously.
- ▪On the CIFAR-100-LT dataset, RefCal achieved superior performance compared to the widely used Correctness Ranking Loss.
