<span style="-webkit-font-kerning: none;" class="">Adaptive and personalized systems have become pervasive technologies which are gradually playing an increasingly important role in our daily lives. Indeed, we are now used to interact every day with algorithms
that help us in several scenarios, ranging from services that suggest us music to be listened to or movies to be watched, to personal assistants able to proactively support us in complex decision-making tasks.</span></div>

<span style="-webkit-font-kerning: none;" class="">As the importance of such technologies in our everyday lives grows, it is fundamental that the internal mechanisms that guide these algorithms are as clear as possible. It is not by chance that the recent General
Data Protection Regulation (GDPR) emphasized the users’ right to explanation when people face machine learning-based (or more in general - artificial intelligence-based) systems. Unfortunately, the current research tends to go in the opposite direction, since
most of the approaches try to maximize the effectiveness of the personalization strategy (e.g., recommendation accuracy) at the expense of the explainability and the transparency of the model.</span></div>

and interpretability?</span></div>
