Gaussian Baseline

• One of the first propositions was to add Gaussian noise to the original image
• Gaussian baseline was introduced by Smilkov et al. @smilkovSmoothGradRemovingNoise2017
• used a Gaussian distribution centered on the current image with a variance σ\sigmaσ.
• This variance is the only parameter when tuning the method
• This is in Smooth-Grad
