https://2023.elixirconf.com/presenters#speaker-aldebaran-alonso-elixirconf-us-2023 In today’s complex and ever-evolving world, the ability to make sense of uncertain and imprecise information is crucial for developing intelligent and adaptable solutions. How can we make a computer understand phrases like “The sensor is too cold” or “Increase the fan speed”? Traditional programming languages often struggle to handle such ambiguity effectively. In this talk, we delve into the world of Fuzzy Logic and explore how it can be integrated into Elixir projects. Fuzzy Logic offers a framework for dealing with imprecise data, incomplete information, and uncertain conditions, making it a perfect match for solving complex problems that require human-like decision-making. During the talk, we will start by introducing the foundations of Fuzzy Logic and its principles. We will then shift our focus to the integration of Fuzzy Logic concepts into an Elixir library called Flex, demonstrating how to model Fuzzy Sets, define Linguistic Variables, and create Fuzzy Rules that drive intelligent behavior with a complete Fuzzy System. Throughout the session, we will showcase a practical example and case studies where Fuzzy Logic has been successfully applied to enhance Elixir applications. Furthermore, we will discuss the benefits and trade-offs of incorporating Fuzzy Logic as an alternative or complement to Control Theory and Artificial Intelligence, as well as future work.
