LeAP: Precise Model Slimming with Learnable Adaptive Permutation for Feature Selection

LeAP replaces costly permutation‑based feature importance with an end‑to‑end learnable module that shuffles features, applies adaptive gradient‑bias regularization, and achieves state‑of‑the‑art sparsity and inference speedups on large‑scale recommender models.
