SmoothGrad: noise-averaged gradient sensitivity maps

Contribution grade

AI interpretability, model editing and data attribution · Human-designed research method or resource

Reference score130,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Averages sensitivity maps over Gaussian perturbations of an input to reduce visually noisy saliency, and studies visualization choices and training-time noise.

Scientific scope

Averages sensitivity maps over Gaussian perturbations of an input to reduce visually noisy saliency, and studies visualization choices and training-time noise. Visual coherence is evaluated on selected image models and does not certify causal faithfulness, completeness or robustness. Monte Carlo averaging approximates a smoothed map, not the exact unsmoothed gradient.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Visual coherence is evaluated on selected image models and does not certify causal faithfulness, completeness or robustness. Monte Carlo averaging approximates a smoothed map, not the exact unsmoothed gradient.
