Why do large language models hallucinate?

The Generative AI Conversations are organized by Professor Vincent Ginis and visiting Professor Andres Algeba, who are respectively the VUB's artificial intelligence officer and coordinator in generative AI. The purpose of these lectures is to clarify and concretize the VUB's guidelines on the use of this new technology. Attendees can expect a thorough explanation of various aspects of generative AI, including how they operate, their effective use, and ethical considerations surrounding data privacy and biases, among others.

The Generative AI Conversations are aimed at the entire VUB community, including students, faculty, researchers, administrative, and technical staff. Each session includes a presentation, supplemented with testimonials and a panel discussion. In addition to the "Why Do Large Language Models Hallucinate" lecture on 18 April, the series includes the following two lectures:

• "The interaction between large language models and the world" (25 April)
• "Large language models and their feedback loop" (16 May)

The lectures will take place in room I.0.03 of the VUB Main Campus and can be attended both in person and online.
