Textbook Group meeting for Parr, Pezzulo, Friston 2022 .

Okay, well, welcome everyone. Thanks for joining. It's September 16th and we are in the third meeting for Cohort 2. We're on our second discussion of Chapter 1 in the textbook. So this is our closing discussion on Chapter 1, which is going to be just our jumping off point into the following chapters. We'll go to the questions page where I saw some questions were submitted. We can also look at other areas, like just the chapter notes more generally. But before we go to the questions, is there any just remarks that people would like to share on Chapter 1? And then otherwise, I'll make one short note about another resource. I'll be watching the hand-raising tip. Well, first, maybe I'll just share this other resource. And it's already added to the resources section and I'll put it in the nearby. It's called Pools of Insight. It's from 1999. However, the author is still around. And when I emailed them, yeah, this is the most recent version. And the document is called Pools of Insight. A previous version, I guess, was called Knowledge Hydrant. But again, this is the most recent version, even though it's almost as old as some of us might be. And it's based around Alexander's, Christopher Alexander's pattern language, which may be familiar to some. It's a very unique book. And it speaks to archetypes in architecture and design and talks about how there's composition patterns and mix of language and grammar for that. And that kind of a pattern language approach has been built on in many other settings. And this work is a very interesting application of pattern languages to learning groups. I think going through it could be interesting for anybody who's just curious about this approach of pattern languages and learning groups. And also, we're very interested to apply this more intentionally as we continue to iterate on the learning groups format in Active Inference Institute, textbook groups for years to come and new textbooks to come and so on. Just looking at the titles, there's a lot of insight. Like the book is a knowledge hydrant. How do we even approach that? The group is like a pool of insight. How do we approach that? You know, how are we going to integrate our individual study with group dialogue? So not much more to say on this today, but if anyone's like excited about that, it would be awesome to hear their, how they see these patterns playing out because a lot of them speak to what we want to cultivate in this group. Okay. Going to the questions page. Again, we'll see we'll see we'll see we'll see we'll see we'll see we'll see we'll see not the room. I'll add it there too. And it's also in resources. You can just look up, you know, pools and you'll find it. People may still add more questions to the page, but we have some really rich questions provided already. So we'll start with a smaller one. In relation to perception action loops, the book states, the possibilities for control and adaptation are plentiful, but very few are useful. I'm not sure how useful is being used here. Useful for evolution, survival, what determines useful? Page four. What does anyone see or think? So I don't know. I would just venture to jump off the cliff and guess that maybe the authors mean like full maintenance of the non-equilibrium steady state density or like existence. Just to guess though. Right. What's the non-equilibrium steady state? It is like the balance of all things that we find ourselves in as living creatures. So like, you know, I'm a human. I have, you know, a certain amount of cells, tissues, and organs. I have a temperature that I expect to find my body at and like a range of temperatures that I can survive in. I need a certain concentration of oxygen. My blood oxygen needs to be maintained at that level. So just like all of the things that like, I need to have a certain amount of water, like, like all of the things that contribute to me being able to persist as in my non-equilibrium steady state. So it's like, you know, if…
