Paving the way from Explainable Fuzzy Systems to Trustworthy AI



In the era of the Internet of Things and Big Data, data scientists are aimed for finding out valuable 
knowledge from data. They first analyze, cure and pre-process data. Then, they apply Artificial 
Intelligence techniques to automatically extract knowledge from data and afterwards translating 
knowledge into products and services for economic growth and social benefit. Trustworthy AI is an 
endeavor to evolve AI methodologies and technology by focusing on generating a new generation of 
intelligent devices which respect non-discrimination and fairness with the ability to explain their 
decisions to humans. Furthermore, when it comes to consider the impact of AI systems on human 
behavior, several dimensions have to be addressed, being the most well-known among them the ethical, 
legal, social, economic, and cultural issues. 
Explainable Fuzzy Systems born with the aim of paving the way from interpretable machine learning to 
Explainable AI. Such systems deal naturally with uncertainty and approximate reasoning (as humans do) 
through computing with words and perceptions. This way, they facilitate humans to scrutinize the 
underlying intelligent models and verify if automated decisions are made based on accepted rules and 
principles, so that decisions can be trusted and their impact justified. Notice that, EXFS automatically 
generate factual and counterfactual verbal and non-verbal explanations. Such explanations include 
linguistic pieces of information which embrace vague concepts representing naturally the uncertainty 
inherent to most activities in the everyday life. 
In this colloquium, we will begin with a non-technical introduction to the field of TAI (i.e., revisiting 
definitions and fundamentals, reviewing the state of the art and enumerating open challenges). Then, we 
will briefly review the history of fuzzy systems from the pioneer works of L.A. Zadeh to the most recent 
developments on EXFS, with special emphasis on fuzzy-grounded knowledge representation and 
reasoning, as well as how to use EXFS to deal with imprecision and uncertainty in the contexts of XAI 
and TAI. Finally, we will see some practical software tools as well as critical issues related to 
psycholinguistic human evaluation.
