Selective classification enables models to make predictions only when they are sufficiently confident, which is crucial in high-stakes scenarios. Previous methods focus on modifying deep neural networks’ architecture to estimate prediction confidence. This work provides a generalization bound for selective classification, revealing that optimizing feature layers improves performance. Inspired by this theory, we propose Confidence-aware Contrastive Learning method (CCL-SC) for Selective Classification, which similarizes homogeneous instance features and differentiates heterogeneous instance features based on the model’s confidence strength. Experimental results on CIFAR-10, CIFAR-100, CelebA, and ImageNet datasets show that CCL-SC achieves lower selective risk than state-of-the-art methods across most coverage degrees. Moreover, it can be combined with existing methods for further improvement.

Imagine a smart model that only makes predictions when it’s really sure about what it’s saying. This is important in situations where you need to get things right the first time. Previous attempts at making these models work better have focused on changing how they think, rather than how they look. Now, we’re taking a different approach by improving the way our model processes information (its “features”). We’ve come up with a new method called Confidence-aware Contrastive Learning for Selective Classification (CCL-SC). It helps our model tell apart similar and very different things, based on how sure it is about its predictions. We tested this method on some big datasets and found that it performs better than other methods in many cases. It’s also flexible enough to be used with existing methods to get even better results.
