Nous pouvons utiliser la fonction intégrée Python map() pour appliquer une fonction à chaque élément d’un itérable (comme une list ou…
Neural networks achieve state-of-the-art accuracy in many fields such as computer vision, natural-language processing, and reinforcement learning. In this tutorial, you’ll specifically explore two types of explanations: 1. Saliency maps, which highlight the most important parts of the input image; and 2. decision trees, which break down each prediction into a sequence of intermediate decisions.
