ASAM:讓鄰域跟著權重尺度ASAM adapts the neighborhood scale
同一函數可用不同尺度的參數表示;量尺也需相應改變。 / Adjust the neighborhood under function-preserving rescaling.
自適應約束Adaptive constraint
T 是正規化算子;球形約束在權重空間可變成橢圓。 / A normalized ball can become an ellipsoid.
尺度相容Scaling compatibility
僅針對保留模型函數的重縮放 A,並要求 T 的相容性。 / Restrict A to function-preserving rescalings.
自適應銳度Adaptive sharpness
以相容的尺度比較同一模型附近的損失。 / Compare compatible neighborhoods.
