Existing compression tools usually address only one side of the problem. Weight pruning (SparseGPT, WANDA) produces fixed masks, while activation sparsity (TEAL) skips small inputs uniformly. Combining the two has so far required extra machinery, such as the SVD components in… ## All works 6 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1.
