Anomaly DetectionOptimizationConvolutional Neural NetworkImage

🎯 What it does: This paper first conducts theoretical and experimental analysis of the existing Activation Shaping method (ASH), proving that its core enhancement of OOD detection is due to scaling the activations rather than pruning; it then proposes a post-hoc method called SCALE that only uses scaling, further improving OOD detection performance without reducing ID accuracy; based on this, the scaling concept is transferred to the training phase, designing Intermediate Tensor Shaping (ISH) for activation weighting optimization during training, thus achieving higher OOD detection performance with lower training costs.
