Visual explanation of simple neural networks using interactive rainbow boxes
Résumé
Artificial neural networks are machine-learning algorithms inspired by biological neural networks. Their main inconvenient is their "black-box" nature: while they are very efficient for making predictions, it is difficult to explain these predictions. In this paper, we propose a visual translation of the reasoning performed by simple neural networks, i.e. without hidden layers. This visualization relies on rainbow boxes, a recently-introduced technique for set visualization, and on three improvements we propose for rainbow boxes, including interactivity. We also present a small application of the proposed approach to decision support in antibiotherapy, for helping a physician to choose an antibiotic in urinary infections. Index Terms-Explainable artificial intelligence (XAI), artificial neural networks, medical decision support, set visualization.
