Computer says no

If you are a fan of Little Britain you are probably familiar with the title of this post, thanks to the different sketches in which a human introduces some data in a desktop PC until, well, the "computer says no". I am currently using some of this short videos as a funny way to introduce one of the main challenges we are facing today when working with Artificial Intelligence systems: algorithm transparency. Explainable AI, or XAI, is an essential requirement of Machine Learning models to understand, trust and manage automated decision systems. Accordind to DARPA, through XAI " New machine-learning systems will have the ability to explain their rationale, characterize their strengths and weaknesses, and convey an understanding of how they will behave in the future. The strategy for achieving that goal is to develop new or modified machine-learning techniques that will produce more explainable models. These models will be combined with state-of-the-art human-computer interface techniques capable of translating models into understandable and useful explanation dialogues for the end user".
