What is generative AI and how does it work? – The Turing Lectures with Mirella Lapata

How are technologies like ChatGPT created? And what does the future hold for AI language models?

This talk was filmed at the Royal Institution on 29th September 2023, in collaboration with The Alan Turing Institute.

Generative AI refers to a type of artificial intelligence that involves creating new and original data or content. Unlike traditional AI models that rely on large datasets and algorithms to classify or predict outcomes, generative AI models are designed to learn the underlying patterns and structure of the data and generate novel outputs that mimic human creativity.

ChatGPT is perhaps the most well-known example, but the field is far larger and more varied than text generation. Other applications of generative AI include image and video synthesis, speech generation, music composition, and virtual reality.

In this lecture, Mirella Lapata will present an overview of this exciting—sometimes controversial—and rapidly evolving field.

Mirella Lapata is professor of natural language processing in the School of Informatics at the University of Edinburgh. Her research focuses on getting computers to understand, reason with, and generate natural language. She is the first recipient (2009) of the British Computer Society and Information Retrieval Specialist Group (BCS/IRSG) Karen Sparck Jones award and a Fellow of the Royal Society of Edinburgh, the ACL, and Academia Europaea.

Mirella Lapata's clarity on the subject. This is very easy even for a Non-Technical person to understand .

[GeorgeZoto]

A fresh air of presenting generative AI from different perspectives, wonderful to watch 😀

[devhims]

Always a great pleasure to listen to these lectures from the royal institution.

I just sat before the screen to learn about AI and saw this video. I knew nothing about AI or Chat GPT, only heard about them. But I was able to understand whatever she said within my own limits. Thank you for this video MS Mirella

When we have complex technologies explained in such clarity and understanding, there is nothing to say but to salute the presenter. Excellent presentation. My 10year old could simply understand the technology behind generative AI / ChatGPT4 and all the inherent benefits and risk associated. Thanks Prof.

Brilliant, outstanding presentation on GenAI! She has put it in such a simple way that anyone can understand! I forwarded it to everyone I know! I strongly believe that the greatness lies in simplifying things and not complicating them! It shows her command and down-to-earth attitude on the subject! She is amazingly passionate! Her last name is "Lapata, " which in Hindi language (plus a few other native East Indian languages) means "Lost, " but in fact, it is reverse in her case because she actually "finds" those lost! For those lost with AI, she found them an easy way! Kudos to her! Congratulations to her and Ri!
