Hi! I'm Victor!
Here's a quick intro :D

These days I focus on ML/AI at Google but have been a teacher, data scientist MLE, etc.

I try to be genuine & positive so when I leave this world it's in a better state than I found it

Best I think people really can do is give compassion & empathy ♥️

Been more or less in all of those problems but my experiences are still unique. And frankly, I don't know how well anything I did in the past would apply to the current state of things

Oh I love it because I literally thought you meant "want" but that actually makes a lot more sense

(new vocab word of the day!)

Victor Geislinger @victorsvector.com · 1d

It's also really funny because I was like 'wow I can imagine this being really great with slides!' and then I saw the pdf at the end lol

I also don't want to be that guy, but I noticed the smallest typo "(as they are often wont to do)"
(but maybe you're going for that human aesthetic 😁)

... and I'm back!!

Wow that was really good— I've been wanting to look at data mesh more closely (I literally have one of the books you mentioned). I really like the idea of federation and feedback loops

So I'm hearing a challenge to read it faster than 30 minutes??

on your marks... get set...

I love that— thanks!!
Definitely moving up my list! (It's available at my library now but I have the Twilight series++ to focus on first lol)

The failures definitely seem more consistent with a ball of relationships over a fundamental 'understanding' of cute concepts that it extracts from

It also more closely matches how neutral nets work compared to something being more emergent with a core concept of how things work

Quick note about the Winograd schema challenge since I say I'm personally not convinced

Some benchmarks show ~95% passing this for some models. But many still question LLMs ability to fully solve. This is in part because we can't tell if it's 'just good at pattern matching' since they still fail

Victor Geislinger @victorsvector.com · 2d

The hard part is defining if enough relationships approximate or are equivalent to a 'world model'. Some folks think LLMs/AI can get there in practice if we make them large enough

Personally, I think 'world model' is one of those concepts that sound concrete but starts crumbling when applying it

It's a good question— for me, I see it as a type of generalization that emerges from using 'known' concepts (not necessarily physical)

Answering what does 'it' refer to in 'the trophy didn't fit in the suitcase since it was too big' requires understanding relative size

some more pictures of the situation

Victor Geislinger @victorsvector.com · 3d

sooo the roof started leaking *bad* in my office

But no worries, we have a siphon going so maybe this will relieve some of the puddle forming above me?
(thanks physics for the assist)

I'm w/ my kids to get a small toy after our family vaccination trip, and after witnessing a complete freakout until ~5s after getting their shots & them being perfectly fine, seeing how it really is just anticipation of the needle

Going to pretend it's metaphor for something but don't know what yet

That's awesome! Congrats on the monthiversary!!

Maybe you were looking for 'resistive heating' but it's still kinda weird calling it that for something like saying my computer is 100% efficient in hear generation

Victor Geislinger @victorsvector.com · 3d

Ooh that looks like it'd be fun to read (especially for today)

Would love to know what you think but for now putting it on my list!

Not going to deny that future developments could produce more capable models that we could say exhibits theory of mind or a world model

But the skeptical scientist in me says it's not yet convinced current models are there (or even close) based on the evidence where models have difficulty

Good reminder to check your local library to see if they have have free access to @oreilly.bsky.social's digital catalog

(you won't be surprised to hear that every Bay Area library I've checked has the O'Reilly catalog available for free)

The Illustrated Guide to AI Agents

New book announcement!

Thrilled that together with @maartengr.bsky.social , we're writing a new book titled “An Illustrated Guide to AI Agents” and published by @oreilly.bsky.social.

Always loved O'Reilly having early releases in their digital library! Really helps when tech is evolving sooo rapidly!

Super curious to see the illustrations for all the different concepts :D

Victor Geislinger @victorsvector.com · 3d

Totally with the **may** here. Haven't been convinced LLMs have a 'world model' like we think of it based on where we see it 'fails'

I find it interesting from these papers seeing connections across different modalities. But I also would think due to language focus it'd pass Winograd first, if ever

Victor Geislinger @victorsvector.com · 3d

Personally, I think the word "clearly" is doing a lot of heavy lifting here XD

LLMs definitely have pattern matching that we would find consistent with a world model but they also fail in some ways that we suspect a 'world model' would have little problem with (like the Winograd schema)

Victor Geislinger @victorsvector.com · 3d

things just got interesting

I still hold up LLMs having trouble with the Winograd schema challenge (en.wikipedia.org/wiki/Winogra...) as the counterexample of them building a 'world model'. But these papers do seem to suggest the opposite is not out of the question
