Choosing how aggressively to prune is hard, because a stricter threshold removes more but can cost accuracy. The claim describes how ASTER measures the effect of the threshold on the loss while training continues, and says that restricting the calculation to batch normalization layers keeps it cheap. If it holds, the threshold could be tuned automatically without a separate retraining step.","findings":["ASTER keeps unpruned filter weights unmodified, which gives scaling-invariance, and adjusts the pruning threshold alongside training.","On ILSVRC-2012, it reduces more than 76% of FLOPs for ResNet-50 with 2.0% Top-1 accuracy degradation.","It cuts 46.6% of FLOPs for MobileNet v2 with a 2.77% Top-1 drop, and 16.1% for MobileNet v3-small with a 0.03% drop."],"terms":[{"term":"L-BFGS","means":"An optimisation method that uses a compact approximation of how the loss curves, so it can estimate second-order effects without storing a full matrix."},{"term":"batch normalization (BN) layers","means":"Layers in a neural network that rescale and shift the values passing through them, with learnable parameters, to stabilise training."},{"term":"sensitivity of the loss to the threshold","means":"How much the model's error changes when the cut-off used to decide which filters to prune is changed."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-25T10:16:30.396Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-25T10:16:30.396Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
