Global explainable artificial intelligence

Abstract

Methods and systems are presented for providing explainable artificial intelligence for a deep-learning model on a global level. Multiple surrogate models are generated based on characteristics of the deep-learning model, where each surrogate model is configured to mimic a behavior of the deep-learning model with respect to one of the output dimensions associated with the deep-learning model. Simulations are performed on the surrogate models. Based on the simulation results, importance scores are calculated for each input feature of the deep-learning model. An importance score calculated for an input feature represents an extent to which the input feature contributes to a corresponding one of the output dimensions associated with the deep-learning model. The importance scores may then be used to modify the characteristics of the deep-learning model or other downstream machine learning models.
