XAI Beyond Explaining

Explainable Artificial Intelligence (XAI) can not only be employed to get an insight into the reasoning process of an Artificial Intelligence (AI) model.

The Information obtainable from XAI can also be leveraged algorithmically, e.g., for guiding a Neural Network during training towards a fair and unbiased use of features, or for increasing its time, memory and energy efficiency (by identifying safely removable non-functional network elements) after training has finished.

Within the recently published paper by Weber et al., (2022) “Beyond explaining: Opportunities and challenges of XAI-based model improvement”, the authors provide a timely survey on how XAI information may be harnessed apart from their illuminating qualities. The authors:

(1) show how and why XAI improves several model properties in toy experiments.

(2) develop a unifying theoretical framework for XAI-based model improvement.

(3) extensively review and discuss existing approaches that use XAI to improve models.

(4) provide experiment-supported practical recommendations for XAI-based augmentation.
