[Documentation request] Equations of LRP rules #224

Closed pmartineauGit closed 2 years ago

pmartineauGit commented 3 years ago

Dear @albermax,

First, thank you very much for the amazing module!

I am using LRP analysis with a simple multilayer perceptron-based classifier but I am unsure about what is going on in the analysis since I was not able to find the mathematical expressions for the predefined rules.

I had a look at https://innvestigate.readthedocs.io/en/latest/modules/analyzer.html, "iNNvestigate Neural Networks!", and "Software and application patterns for explanation methods", but I could not find any description of the rules listed in innvestigate/innvestigate/analyzer/relevance_based/relevance_rule.py

Could you please point me to some reference describing the LRP rules?

Thank you very much, Best, Patrick

Hi, you could have a look at https://arxiv.org/pdf/1910.09840.pdf and also at http://www.heatmapping.org/tutorial/

For the code you have to look at relevance_rule_base.py you find it in analyser/relevance_based

Best
