Watch the Q&A: • Q&A: What is generativ...
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 .
A fresh air of presenting generative AI from different perspectives, wonderful to watch 😀
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
so beautifully presented honetly just so relatable, refreshing and just the right blend of everything !
She is so real and passionate about what she is talking ❤
Mirella Thank you , You are full of wisdom like Athena !
Excellent and clear lecture for the general public! It’s meant to be a divulgation lecture
amazing lecture.. loved the way Merella explained each aspect of GEn-AI without going into much technical details..
Brilliant, the best talk on Gen AI for a layman and techie alike. Kudos Ms Lapata
This is great and presenter is very clear about her explanation , I would suggest to everyone must watch. Thanks !!
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.
Very clear delivery of a complex topic thanks
This presentation is very easy to follow and understand. Great!
incredible lecture. thank you so much TRI and Mirella!

This was a great introductory lesson on AI. Mirella is very knowledgeable, and her presentation keeps your interest. Please continue to produce these videos!
What a wonderful and knowledgable speech!
Excellent lecture performed by Mirella ! So much things learned
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!
good video and clear explanation for everyone to understand. well done Ms. Mirella Lapata

Gorgeous professor ❤❤
Excellent introduction. Thank you Mirella and RI.
Great presentation...Thank you
Wonderful! you are ...simply Great!!
Excellent excellent Lecture
Lovely presentation!
I hope that others have realized that, given the model she presented of different types of brains compared to the human mind/brain, it is now clear that size doesn't necessarily equate with extreme intelligence. Certain LLMs are already smarter than humans regarding certain IQ metrics -even though they have way less parameters!
Very good presentation
I really enjoy this lection😀
Thanks, helped a lot
Very simply and nicely explained Gen AI
I learned a lot from this lecture and Ms Lapata was an engaging lecturer. Obviously this is a super-top-level view of AI, which is what I needed. The mind boggles. I feel her optimistic summary is maybe too optimistic as it assumes a lot of benevolent actors in the future and also that bad actors will always act logically (predictably) and mitigate harm, which seems almost child-like in its naivete....after all, we've known about climate change and its connection with human activity since the 1950's and look where we are today. Not terribly reassuring.
A wonderful session.
great presentation on GenAI..👍
Excellent presentation
Really insightful lecture! For anyone interested, here are some key takeaways:
1. Generative AI can produce content across various formats, including texts, images, and code, by learning from vast datasets.
2. Google Translate and Siri are simpler forms of generative AI already integrated into everyday technology.
3. ChatGPT operates on the principle of language modeling, predicting continuations of given text based on learned data.
4. Despite their capabilities, generative AI models often require further tuning to align with human needs and expectations.
5. The societal impact includes both potential benefits in automating tasks and risks such as job loss and the spread of misinformation.
6. The technology can also be misused to create convincing fake content, posing challenges when it comes to information integrity.
What was your main takeaway from the lecture?
Well that clears that up
Love it ❤
Regarding the ARC testing (which I presume was meant to 'allay fears') it clearly states that there was no task-specific fine tuning. Almost all the bullet point tasks seem simpler to train to than recognising and understanding natural language. It would appear that a rogue state could develop an AI, with such task-specific training. I'm not trying to be alarmist but it should be understood that virtually all academics are (rightly) excited by the technology but give very little thought to its applications outside their spheres of interest. Those with a 'hacker' mindset would likely be able to quickly pervert future LLMs or whatever comes next, to perform tasks it was never designed to do. As better understanding of the fundamentals of this technology spreads I hope we can have more in-depth discussions about real-world ways to avoid issues. (Very enjoyable talk, from someone clearly both knowledgable and enthusiastic about their field)
Most commenters just say how great the video is. Nice to see someone point out something other than that.
A little correction. Berners-Lee didn't invent the internet, he invented the web - the intuitive user environment interlinked and formatted by hypertext that is carried on the internet. An understandable slip though, since the vast majority of people have only ever interacted with the internet through this construct.
Good video.I learn from it about generating AI thanks🎉
amazing lecture!
indeed
Great!
🎯 Key Takeaways for quick navigation:
27:15 🚀 Scaling AI models with more parameters enables them to handle a wider range of tasks.
28:21 🧩 Fine-tuning is crucial to align AI models with human goals and adapt them for specific tasks.
29:54 🤖 Creating AI systems that are helpful, honest, and harmless is a challenge, requiring user instruction and bias avoidance.
31:28 🎯 Fine-tuning with human preferences is key to making AI models more aligned with user needs.
37:42 ⚙️ Despite fine-tuning, AI models like GPT can still struggle to follow instructions, highlighting alignment challenges.
38:12 📜 Regulating AI models is complex, with potential societal, energy, and job impacts.
43:27 🤔 Concerns about superintelligent AI are tempered; we'll likely have specialized AI tools, requiring risk mitigation, not prevention.
44:57 📝 AI regulation is on the horizon, akin to regulations for other risky technologies like nuclear energy.
Made with HARPA AI
Thanks!
Great lecturer
AI made simple. excellent lecture for simple folks like me.
Berners-Lee invented the World Wide Web, not the internet.
Great talk... As a small correction, Tim Berners-Lee didn't invent the internet, he invented de World Wide Web (www) and protocols associtated.
many mistakes were made, I assume it's overexcitement on Mirella's part
Exactly. A geologist making the distinction mistake would be entirely excusable - an AI specialist, not so much.

A.I. , as it stands today, it is computational statistic model. Generative A.I. is statistic model of action based on the A.I. model.😊
An amazing presentation on one of the crucial topic in the age of Artificial Intelligence! So exciting to see the simplicity and flow of clearly understanding the core principles of the subject. Thank you Prof for this lecture!
“Understanding WHAT” level - flat flat flat and non-sense. Try to think.
As we are using data from dfrnt sources like quora etc ,how we are going to train the model in future because may we will have less data in future.as all people will move to gen ai for their ans.
nice session
Excellent presentation! But I found one glitch at 43:11: Time Berners-Lee did not invent the internet, but the WWW.
Horses : All those Cars took our jobs..!
Pp0pp
this is a very very general intro about gen ai
This lecture actually is displaying the logical and creative limitations and boundaries of GPT. I am certain many people reading my comment will be outraged. That’s what is expected.
At 18:50, if I recall correctly, she asked how many knew about transformers, and got a good amount of applause. I really wonder what percentage thought she was asking about giant robots, and how many thought she was referring to devices that change electrical voltage. It was more applause than I would have expected.
Yeah, she's thinking her audience is from kindergarten.😅
I came to the comment section looking for this comment.... i completely agree :)
@@NatalyRobles00 I got confused when they apllauded
damn, that's so cool
