Symposium: Generative AI, Free Speech & Public Discourse

Columbia Engineering and the Knight First Amendment Institute at Columbia are co-hosting panels with multidisciplinary experts to debate artificial intelligence and its impact on the future of public discourse, free expression, and democracy.

About this Event

Generative AI tools like ChatGPT and Dall-E can aid society in a number of ways, but could also bring a fresh deluge of disinformation, threaten free elections, and destabilize democracies. As these tools become widely available, cheaper, and more powerful, how can self-governing societies limit the potential of generative AI to shape — or distort — public discourse? How might we harness technology to address some of the feared harms resulting from the use of generative AI? Which harms require political solutions? What goals should guide our work over the next decade?

This event will feature several keynote speakers and panel discussions with experts from law, computer science, social science, history, and other disciplines. Our guest speakers will discuss topics ranging from AI and human creativity, information integrity and power and governance.

Keynote Presentation Abstracts

Opening up the language model black box

Tatsunori B. Hashimoto, Ph.D., Assistant Professor, Stanford University

Advances in large language models have brought about exciting advancements in capabilities, but the commercialization of this technology has led to an increasing loss of transparency. State-of-the-art language models effectively operate as black boxes, with many things unknown about their training algorithms, data annotators, and pertaining data. Reasoned public discourse about language models requires a deeper understanding of how these systems are constructed, and this talk will mention several approaches — including open-source models and benchmarking, watermarking, and membership inference — for gaining important insights into the behavior of these language models.

Challenges for Conversational AI in the Era of LLMs

Dilek Hakkani-Tür, PhD, Professor of Computer Science, University of Illinois Urbana-Champaign

Recent large language models (LLMs) have enabled significant advancements for open-domain dialogue systems due to their ability to generate coherent natural language responses to many user requests. However, these models suffer from limitations, such as, hallucination, undesired capturing of biases, difficulty in generalization to specific policies, and lack of interpretability. To tackle these issues, the natural language processing community proposed methods, such as, injecting knowledge into language models during training or inference, retrieving related knowledge using multi-step inference and API/tools, and so on. In this talk, I plan to provide a brief overview of our and others’ work that aim to address these challenges.

AI and Trust

Bruce Schneier, Lecturer, Harvard Kennedy School

For AI to be trusted, it must be trustworthy. This won't happen with the current market incentives. If we are ever to realize the full potential for generative AI in public discourse, we need something different.
