In this conversation, Tim Scarfe and David Foster, the author of 'Generative Deep Learning,' dive deep into the world of generative AI, discussing topics ranging from model families and auto regressive models to the democratization of AI technology and its potential impact on various industries. They explore the connection between language and true intelligence, as well as the limitations of GPT and other large language models. The discussion also covers the importance of task-independent world models, the concept of active inference, and the potential of combining these ideas with transformer and GPT-style models.

Ethics and regulation in AI development are also discussed, including the need for transparency in data used to train AI models and the responsibility of developers to ensure their creations are not destructive. The conversation touches on the challenges posed by AI-generated content on copyright laws and the diminishing role of effort and skill in copyright due to generative models.

The impact of AI on education and creativity is another key area of discussion, with Tim and David exploring the potential benefits and drawbacks of using AI in the classroom, the need for a balance between traditional learning methods and AI-assisted learning, and the importance of teaching students to use AI tools critically and responsibly.

Generative AI in music is also explored, with David and Tim discussing the potential for AI-generated music to change the way we create and consume art, as well as the challenges in training AI models to generate music that captures human emotions and experiences.

Throughout the conversation, Tim and David touch on the potential risks and consequences of AI becoming too powerful, the importance of maintaining control over the technology, and the possibility of government intervention and regulation. The discussion concludes with a thought experiment about AI predicting human actions and creating transient capabilities that could lead to doom.

I saw this interview while being high and English not being my mother tongue. I managed to understand the fluidity in between your concepts. This was Filosofía.❤

[gaz]

The cadence of this podcast was excellent. Some very complex ideas were bounced around with fluidity and lots of gentle challenge. 2 hours completely vapourised - excellent!

[bytesizedbraincog]

Before comments, I spend my walks in Syracuse (very peaceful in summer) hearing to these podcasts, I sometimes hear in loop to make sure I consume, think about it and revisit. Not just saying, if there is a fan club for Tim, I would be the first one in the list! ❤❤

1. First of all - setting the right expectations - we are still beginners in this field - As a grad, I see people expecting 5 years of experience in Generative AI and not about the basic principles. David mentioned it very humbly.
2. Borrowing concepts - I see this “SIMPLE” analogy could drive many complex tasks. Like Alpaca borrowing instruction sets from GPT-3. “ Those who understand it are the ones who can take advantage of” - Brilliantly put.
3. Yes I do see how the autoregressive works and we just modelled a complex human language with probability - it’s fascinating. I like when John mentioned about Memory augmented transformer and a concept of “abstraction space”.
4. Sometimes I do think, do we really need that conscious experience from the models, or it should be an augmented trigger for humans to better express themselves in this world with this powerful language understanding capability.
6. There are laws of scaling in data, models etc, I always think about “bringing alignment” in smaller use cases. Connor (alignment guy) mentioned in one podcast, We shouldn’t move towards bringing bigger scope of predictions until we sit and think about the problem of alignment. “Iterative approach” is sometimes a boon and a bane - hyping about something and then goes down again. We are not underplaying the problem for sure, but at the same time overplaying the autonomous behaviour.
7. There was a good talk from Eye on AI -  Professor Yoshua Bengio has mentioned Generative Flow Networks - learning to do reasoning with world knowledge (retrieved from World Model) - cross knowledge sharing and learning! It has an Inference model - which does reasoning - If it hallucinates then it will have a penalty based on the world model and a language model that expresses the information in a well-crafted manner. Wonderful conversation 🚀
8. Anthropic announced 100K context window - I have this thought about the impact of context window size. 'chunking and making multiple inferences' vs 'higher context length results' -> humans might have multi hop pattern - hence attending to important info in multiple hops vs "attending to huge info which may have many unnecessary info" - Any thoughts on this one? As there is one way of doing it Vector DB + retrieve important + generate with context - Thinking about the question of "context window" might be critical for all NLP SAS companies. Tim absolutely nailed it - in high resolution - we have higher semantic map. RAG (cosine, dot) - does not have higher precision. There is not much flexibility around it. "model deciding where to attend" vs "we influencing where to attend with (not much flexible) measures of cosine and dot product similarity.

Overall, I enjoyed it! 🧠🚀

This episode is excellent. The guest is incredibly knowledgeable, quick, and keeps up with topics ranging from Free Energy principles to Copyright concerns. I wonder if he would like to be an MLST co-host 😁?

[andrealombardo]

Appreciate a lot the summary in each chapter of the video. These details make the difference, thanks!

[mgostIH]

In a recent video, Yannic demonstrates a method for turning transformers into RNNs, addressing context window limits.
It's very nice to see Tim drawing insights from his previous hosts and countering arguments against GPT as an agent. However, David seems to hold contradictory views, expecting both limitations in AI expertise when talking about education and full automation in fields outside his own like music.

Regarding multimodality, David may be underestimating the potential generative models working on learned discretizations like Parti: a VQVAE can learn how to handle general audio without us having to worry about music notes or other hand chosen features. The PaLM-E paper demonstrates how this can even work for reinforcement learning, where language models can already act as agents and perform tasks in the environment. David might not fully appreciate the impact of scaling computational power or embrace Sutton's Bitter Lesson.

[alertbri]

About 75% in I found the conversation got very interesting, talking about education, hyperpersonalisation, interpolation, music... Really good flow of conversation 🙏 very enjoyable.

[lakhanpatel]

I'm currently reading second edition of this book, it is amazing. No book in the market that cover these broad topics in single book. Thank you for discuss in more detail.

[CristianVasquez]

Really interesting guest, thanks for the interview!

[paxdriver]

Shout out to Karl Friston, you guys are awesome. Thank you so much for all your hard work Tim, this is by far my favourite content on YouTube.

[zandrrlife]

🔥. Appreciate the content. Going to watch this its entirety tonight. I see we're talking talking today ha.

[AISynthetic]

Read the first edition @David Foster did a great job in explaining and covering all generative AI tech in a single book. Eager to read the 2nd edition.

[codediporpal]

I'm so excited to get this book. I still find the learning experience on technical subjects provided by a well done book to be superior to video courses, or just trying to figure it out from material on the WWW. (+ code example/exercises of course).

[SeekingTrueHappiness]

Listening to this podcast made being stuck in traffic for 2 hours almost tolerable. Very thoughtful exchange of ideas in this podcast. I was really curious to know whether there was a viable alternative to the Turing test now that ChatGPT has shown that language doesn't equate to intelligence. So the comment Tim made about the capability of these systems opened a new way for me to think about all these things.

[sabawalid]

Anither great episode. Very interesting guest.

GPT-4 Modified: David Foster posed an intriguing query in the "Language and True Intelligence" section, invoking the timeless "chicken-or-egg" dilemma about the origin of language and intelligence. It's a fascinating conundrum, and my stance aligns with John Searle's perspective that intelligence predates language. However, I assert that language, once in place, is the catalyst that triggers a quantum leap in our intelligence.

Delving deeper into Foster's discourse, he brilliantly frames language as a high-level compression algorithm. This, I believe, is the raw power of language, encapsulating vast amounts of sensory data into manageable, bite-sized chunks. It enables humans to transmute a plethora of sensory inputs into a compact set, and once these words are anchored to sensory experiences, our cognitive juggling capacity skyrockets. This broadens our mental bandwidth, empowering us to handle and reason with significantly more information than other species.

Take, for instance, the concept of the Earth. Through the potency of grounded words, we, as humans, can encapsulate the enormity of 200 million square miles of land in a single term: Earth. This remarkable ability extends to countless levels, granting humans a superpower to reason across a myriad of compositions, as extensive as our senses and tools can perceive.

Therefore, my contention is that intelligence is the foundation, the original seed. But it is the advent of language that unfurls this seed into a grand tree, catapulting our intelligence into previously unimaginable dimensions.
