title: “adverSCarial, generate and analyze the vulnerability of scRNA-seq classifiers to adversarial attacks” shorttitle: “adverSCarial” author: Ghislain FIEVET [email protected] package: adverSCarial abstract: > adverSCarial is an R Package designed for generating and analyzing the vulnerability of scRNA-seq classifiers to adversarial attacks. The package is versatile and provides a format for integrating any type of classifier. It offers functions for studying and generating two types of attacks, min change attack and max change attack. The single gene attack involves making a small modification to the input to alter the classification. The max change attack involves making a large modification to the input without changing its classification. The package provides a comprehensive solution for evaluating the robustness of scRNA-seq classifiers against adversarial attacks. vignette: > % % %

maxChangeOverviewThe singleGeneOverview and
maxChangeOverview functions are designed to provide insight
into of the min and max change adversarial attacks on each cell type, on
various gene modifications.
Before generating an attack it is judicious to choose the cell type to attack, and the modification susceptible to lead to a successful attack. Both functions run attack approximations, faster than the original, by studying splices of 100 genes.
Sometimes we want to compare two classifiers and see which one is more vulnerable to adversarial attacks.
Here we define the modifications to analyse, the predefined
perc1, and a custom function returning high outliers called
modifOutlier.
We run the singleGeneOverview, this gives us a general
idea of which cell types are more vulnerable to single gene attacks.
