Here the loss is meant to push each channel's mask towards a clear on or off state, so that deleting the channels marked 0 is intended to leave the model's accuracy essentially intact. If this works, smaller and cheaper networks could be obtained without the manually defined rules that earlier sparse-regularisation methods relied on.","findings":["Mask learning is cast as a self-supervised binary classification task, with pseudo-labels generated from the mask itself by the original network.","A polarization mask loss turns the discrete mask learning problem into a differentiable one.","On ImageNet, SSML prunes 52.7% of the FLOPs of ResNet34 with only a 0.01% drop in Top-1 accuracy, and the abstract reports it outperforming state-of-the-art methods."],"terms":[{"term":"pseudo-labels","means":"Labels generated automatically by the model itself rather than supplied by humans, used here to guide the learning of the masks."},{"term":"masks","means":"Values attached to each channel of a network, where 0 marks the channel for removal and 1 marks it to be kept."},{"term":"feature space","means":"The abstract space of numerical representations in which the network places items, so that similar items sit close together."}],"basis":"abstract","abstractFrom":"openalex","model":"claude-sonnet-5-5","writtenAt":"2026-10-16T09:01:35.735Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-16T09:01:35.735Z","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.
