The systems that no one will test | Terra Incognita
This happened to me in 2020, and it has been on my mind again lately. During the worst of the pandemic, I found a vulnerability in a system that gave me access to the Brazilian federal system, and wit...

Gemma3n was released a few months ago, I wasn't able to find more info and I found it a *very interesting* architecture with a lot of innovations (Matryoshka Transformer, MobileNetV5, etc), so I decided to dig further, here you are the slides of this talk: drive.google.com/file/d/15hbh...

I feel I can build an entire benchmark dataset with ONNX errors that would be harder than the humanity's last exam dataset for us to evaluate AGI

"Optimizers Qualitatively Alter Solutions And We Should Leverage This" (arxiv.org/abs/2507.12224), very nice to see this direction of understanding what different optimizers bring in terms of solution properties.

Not to mention this passage below from his "Du mode d’existence des objets techniques", models today are proving the viability of a structure similar to a natural structure, and we are now submitting models more and more to inductive study because they bear scientific value. 2/2

I find incredible how much we can relate about the evolution of Machine Learning in the past decade to what Simondon described in 1958. The shift towards more generalist systems is exactly what Simondon's concept of "concretization" is about. 1/2

This is absolutely *charming* in its straightforwardness. All kinds of bells and whistles suggest themselves at once, but this gives "really strong baseline for the general case" vibes.

Given the amount of different definitions of world models, at this point, I think I can call any model a world model.

I think the Google Search Appliance (GSA) was a nice concept that suffered a unfortunate timing. Imagine it today with on-premise LLMs, multi-modal document indexing and modern retrieval. All local wo/ any data sent to cloud. I really want to develop a prototype w/ a Jetson.

That can partially explain the similarities of DeepSeek-R1 CoTs and o1-preview CoTs, even though the CoTs from o1 are hidden. There are now probably 3 hypothesis: 1) convergent behavior 2) distillation (but not of CoTs) 3) sinister data leak (directly or through a 3rd party)

Now, independently of regulation, states and legislators need to make very clear that: make no mistake, since these systems are derived and relational, *humans remain ultimately responsible* for its actions and oversight. 4/4.

Christian S. Perone @cperone.bsky.social · 24/01/2025
In that sense, agents' agency nowadays is mediated (it is derived from humans design), relational (comes from interaction) and limited, but it doesn't mean this won't change, and I think that Yoshua Bengio and others are quite correct in understanding the uncertainty of it. 3/4

Christian S. Perone @cperone.bsky.social · 24/01/2025
One thing is an agent having the ability to operate and take decisions within its boundaries (within the operational domain the were designed) and another complete different thing is full agency. We are still (today) grounded in human intentions, designs, and oversight. 2/4

Christian S. Perone @cperone.bsky.social · 24/01/2025
Discussions around AI agents would be much more productive if we just make clear the difference between functional autonomy and vs ontological agency. I can see many folks talking past each other because the lack of understanding of these two different types of agency. 1/4

Finally finished an article I was working on since past year on Gilbert Simondon's philosophy of technology and how it relates to AI/ML. Simondon's philosophy radically changed my views on technology, anyway, here you are the article: blog.christianperone.com/2025/01/note...

If one watches AI competition carefully, it can be weird to see one company saying they need to take *drastic action*, while another company has a *drastic research* team. IMHO, when everything is portrayed as drastic, then nothing really is, as this often leads to nihilism.

Christian S. Perone @cperone.bsky.social · 17/12/2024
I think that Ilya's talk in NeurIPS is just another example of how ML researchers/engineers cannot protect themselves enough against misrepresentation when they speaking in public. I wish we had the same level of scrutiny for futurists spreading historicism as well.

Optimizers in deep learning are a concrete example of how we can move forward and develop very useful algorithms without knowing what is actually going on 😅
