Definition

Out-of-distribution (OOD) detection identifies inputs that fall outside the scope of the training data distribution. Models often perform poorly or confidently incorrectly on OOD data, leading to unreliable predictions in real-world scenarios. Detecting these anomalies is crucial for safety-critical applications like autonomous driving or medical diagnostics, ensuring the system recognizes when it lacks sufficient knowledge to make a safe decision.

Summary

Data points that differ significantly from the distribution seen during the model’s training phase.
