Nice point by @GrandjeanMartin : one of Moreno's sociogram has something hidden that you see if you use a modern layout.Moreno separates boys and girls and indeed they are poorly connected. But there is a group of girls that bridges them, and is equally connected to boys and other girls.A better visualization requires less assumptions.

@tiago @GrandjeanMartin @netzschleuder Moreno chose to use the gender for his visualization. As a result, we can see the relative lack of links between boys and girls, but that is all.The modern layout allows to see that there two groups of girls, one of which has no connections with the boys.This is an objective description of the network, that does not depend on the visualization. But not every visualization allows to see it.

@tiago @GrandjeanMartin @netzschleuder The groups I picked here are such that the kids are more connected to the kids of the same group than to the kids of other groups.So you could see those groups as assortative but it does not mean that other groupings are invalid. I only use the groups to write a description.

@tiago @GrandjeanMartin @netzschleuder A pretty big if! Facts don't care about Moreno's intent (or mine). The description is what it is. It does not exist as a function of a goal.Then when the description is convoked in an interpretation, what happens depends on that interpretation. It's on the interpreter, not the description.I only described here. It's a reasonable fact that some things are not visible in Moreno's viz.

@tiago @GrandjeanMartin @netzschleuder Objectivity is never pure: agreed.Multiple equally objective descriptions coexist: agree.Descriptions come with suggestions: agreed. One cannot extirpate the suggestion out of the expression.But that does not mean that there is a hidden agenda. I'd say we just live with the annoyance of the implicits of the layout, that we use to describe because it begs questions, yet not to answer them.

@tiago @GrandjeanMartin @netzschleuder @graph_tool The problem for me is that the clustering unnecessarily enforces boundaries that do not exist. The Alps exist without a border, so do topological clusters. The limit of the Mont Blanc is an artifact.

@tiago @GrandjeanMartin @netzschleuder @graph_tool Oh but remember that I disagree on that very last point. Just mentioning it for completeness. I'm too tired to continue today!

@tiago You give me a network. Although I need to know where it comes from to interpret it, I do not to describe it.In the version of Dune written by random typing monkeys, the Emperor still betrays Leto Atreides. The text is the same, and we can describe it.

@tiago Borges has a story where a dude named Pierre Menard rewrites the Quixote to the exact word. It's funny because the exact Quixote text in that version means something different, precisely because it is written by someone else.The text is the same and the meaning is different.The description is the same and the interpretation is different.

@tiago You give me a network that comes from a generative process where you have planted a certain structure. We must interpret it a certain way. You've made that case and I agree.

@tiago I find a network and you come to me with the exact same network. You come and you tell me that my interpretation is wrong because in your exact same network come from a place where my interpretation makes no sense. But in fact, your interpretation only applies if my exact same network comes from the same place as yours, which is does not. Your network is written by Cervantes and mine by Pierre Menard, and they mean the same thing.

@tiago Just because you plant hard clusters and generate a blended network does not mean that blended networks necessarily hide hard clusters. Even the exact same networks.

@tiago You give me a network. Two given nodes are, or are not, connected. That is just a fact, an objective description. I do not need to know where the network comes from.With that network either I can make groups of densely connected groups, or I cannot. Objective description. But what it means depends on where the network comes from.

@tiago Groups are a useful trick to describe, but not inherently necessary. Layout-based descriptions have one less unnecessary thing than group-based ones. At least where no groups are given a priori, and although they have other issues.A Bayesian inference with a group-less model is possible, I assume. But even just formulating this model is hard. I've tried and failed. So far.

@tiago The drawbacks of the layout do not invalidate its benefits.

I had to use this trick with Mastodon like I had to with Twitter. The timeline of who I follow has too much bandwidth. I don't read it entirely, of course, and important but low-bandwidth accounts get lost in it. It's diluted.So I have a private list with just those accounts, so I don't miss their posts. Those are like a slow lane added next to the highway, the timeline that I actually watch.Low-bandwidth social media is what I actually like to read. I like the rest as serendipity.

@tiago Nice! It might be worth writing something on how to repurpose social media for academics. I also have off-label uses of vanity metrics.BTW I just deleted the Twitter app from my smartphone, although I keep posting on Twitter. I don't see any of their ads now.I am sure better UX will emerge for Mastodon on every platform, now. We would pay for that.

I suspect that the French get some immunity to AI hype from the sole fact that every time they read "GPT" they hear "j'ai pété" which translates to "I farted". How to take it seriously?(Note: if not for such content, why even toot?)

"The point of these experiments isn’t to diminish LLMs. It’s to show that many of their 'human-like' characteristics are a consequence of the contextual hints we provide, of the fairly rigid response templates reinforced via RLHF, and — above all — of the meaning we project onto the model’s output stream."https://lcamtuf.substack.com/p/llms-are-better-than-you-think-at
