Overconfident Prediction
Overconfident prediction in machine learning models, where predicted probabilities inaccurately reflect the model's true uncertainty, is a significant problem hindering the reliable deployment of AI systems. Current research focuses on improving model calibration through techniques like modifying loss functions (e.g., focal loss variants, entropy regularization), employing novel normalization methods (e.g., logit normalization, hyperspherical projections), and leveraging ensemble methods or Bayesian approaches to better quantify uncertainty. Addressing overconfidence is crucial for enhancing the trustworthiness and safety of AI in high-stakes applications, such as healthcare and autonomous driving, where accurate uncertainty estimation is paramount for responsible decision-making.
