It uses a genetic algorithm to automatically design an activation clustering combination strategy that minimizes backdoor attack success rate under a detection-performance constraint. On the Power System Attack Datasets with 37 classes, it keeps 91.4% average accuracy and reduces BASR from 98.89% to 0.00%.","solution":"The proposed EvoACC-BD-MIDS method itself is the defense; the source does not describe a separate patch, fixed version, configuration change or workaround.
