LRP-γ and LRP-Ɛ Rules
Learn about different LRP propagation rules that favor positive contributions and make saliency maps sparser.
We'll cover the following...
Though the basic propagation rule for LRP works very well in most cases, it can sometimes lead to noisy maps. To remove noise and have sparser saliency maps, we will look into other propagation rules one can use in LRP.
LRP- rule
This LRP rule favors positive contributions rather than negative contributions. The rule can be written as follows:

LRP- rule
This rule enhances the basic LRP rule by adding a small positive
