F-WANDA: Fisher-Reweighted Post-Training Pruning for Sustainable Deployment of Large Language Models
F-WANDA is introduced, a drop-in modification of WANDA that reallocates the per-row keep budget across output neurons in proportion to the empirical Fisher information of the pre-activation, placing F-WANDA on the Pareto frontier of quality versus pruning cost for sustainable LLM compression.
