The Association for Human Mathematics (AHM) statement on OpenAI’s October 6 release of mathematical documents just dropped! www.ahmath.org/statements
AHM Statement on OpenAI’s October 6 Release of Mathematical Documents

Yesterday, on October 6th, 2026, OpenAI – which is currently defending lawsuits against accusations of illegal plagiarism, copyright infringement, and trademark dilution – released a repository of manuscripts purporting to contain solutions to a number of high-profile problems in mathematics.

Mathematicians did not ask for this work to be done. The Advisory Group on Mathematics and Artificial Intelligence, from whom OpenAI has claimed to derive its legitimacy, opened their initial advisory statement by saying that frontier AI corporations should not test advanced mathematical problems on internal models. In ignoring the central premise of the Advisory Group’s position, OpenAI has indicated total disregard for the norms of scientific research — norms that guarantee that mathematics remains trustworthy, ethically researched, and in the public interest.

Mathematicians have a particular vision of progress that is informed by history and field-specific considerations. We reject OpenAI's assertion that this release advances our subject, and we urge mathematicians and the public to view the value of this publication model with due skepticism. 

Releasing over 700 files at once is not a demonstration of scholarship, but a demonstration of power. We urge mathematicians to discontinue their work with OpenAI and to return to a vision of science that centers human understanding.

Why is more quantity coorelated with lower quality? Salami papers existed before AI? In my opinion, it is the user not the technology. Cheating, plagiarism, paper mills, salami papers, etc.. existed before AI.

I can't argue against that, but this is a problem with the tool maker? Factoring out the tool maker, we have in our hands a technology, if used right, has the potential to greatly accelerate productivity. In my opinion, the quesion is not "to AI or not To AI", it is "Centralised AI vs Decentralised"

Is the function space of ANNs involves anything that involves a network of computing units? Will architectural innovations be independent of biological motivations or not? In my opinion, the breakthroughs in AI is based a corpus of studies in fields like neuroscience and psychology. 2/2

Karim Habashy @krhab.bsky.social · 04/10/2026
I think it would be great if we can define what is an AI paradigm? What is the function space of ANNs? Where will the architectural innovations come from? For example, is the AI paradigm building bigger models with larger contexts and feeding more data? 1/2

Karim Habashy @krhab.bsky.social · 04/10/2026
True, and I would argue that this is an accountability problem and not a technology problem?
210
Karim Habashy @krhab.bsky.social · 03/10/2026
Once the above points are clear, promoting them and upholding them through accountability is a convenient next step to take. If there is failure in upholding accountability then this a problem about how accountability is upheld.

Karim Habashy @krhab.bsky.social · 03/10/2026
The next question is, what defines fraudulent? In academia, is producing a huge body of research in a record time fradulent? Is it the quality of the research? Is it comprehensibility and accessibility? These kind of points should be made clear so as to remove a lot of confusion. 2/n

Karim Habashy @krhab.bsky.social · 03/10/2026
In my opinion, AI has merits. I consider it as a tool. As a tool, its impact depends on the provider and the user. The provider is a different topic, so I will talk about the user. Now if a user uses it in a fraudulent way, is it the problem of the user or the tool? I think it is the user. 1/n

Karim Habashy @krhab.bsky.social · 03/10/2026
Good point, but then this can be made a problem of ethics? Can it be compared to plagiarism? In my opinion, advocating accountability and ethical behaviour is one of the ways these problems can be mitigated.

Karim Habashy @krhab.bsky.social · 03/10/2026
I agree and that is a problem. Also, in my opinion, influence has been a side project of media and technology, and it seems more prevalent and approachable through AI use. I don’t know, maybe more awareness and decentralised local AI can solve these problems?

What is the difference between being influenced by an article online and by what Claude wrote? I would question things if the author didn’t screen the output. In my opinion, screening and taking responsibility of what is written is the final verdict.

In my opinion, AI articles need to deferentiate between two definitions of AI aligenment: 1) AI systems act in accordance with human values, goals, and intentions. 2) AI systems do as you were told precisely by their creators. There is a big difference between the two!

Ok, I will be precise here, they do the analysis correctly, but they output the diagram wrong. The model system is x_dot = 1 + ax + x^2, where ‘a’ is a parameter. I checked it again now and they corrected the diagram, but I have the history anyways.

Now published @commsaicomp.nature.com with @neural-reckoning.org We: 🤖 Define a taxonomy of neural network architectures (here 128 unique structures) 🦾 Train > 25,000 models on different navigation tasks #RL 🧠 Link each architecture's behaviour to its memory dynamics doi.org/10.1038/s444...
A taxonomy of recurrence. We defined a family of neural networks for exploring questions in neuroscience and machine learning. Here each network is represented by three circles joined by different connections (short, coloured lines). Networks are joined by longer, pale grey lines if they differ by one connection. Moving from left to right takes us from the simplest to the most complex network.

Finally, we show that our approach, as a surrogate for the genomic code, can provide one of the highest forms of functional compression when evaluated on the MNIST benchmark, achieving ≈ 95% accuracy with only ≈ 1800 parameters.

Later, we showed that our approach is beneficial for encoding innate functions that support generalizations based on a factorial code. This was demonstrated by contrasting our approach in the hidden layer against a baseline where the hidden weights are directly encoded.

Karim Habashy @krhab.bsky.social · 13/08/2026
For results, we first show that indirect encoding is sufficient to produce V1 orientation maps with the associated line filters (left map and filters). Furthermore, these maps emerge more efficiently when utilizing our approach of decomposing the layer into a kernel plus its associated rotations.
100
Karim Habashy @krhab.bsky.social · 13/08/2026
The core method is that the filters of a neural network layer can be represented by a single kernel that is differentiably transformed (rotated) along the spatial dimensions of a layer, and these rotations can be acquired by an indirect encoding network.

Looks like if you're one of the 300miliion who ever took a MOOC with Coursera or Udemy, your data just got turned into assets for Andrew Ng's latest "AI native" edtech "personalized learning" scheme, which Coursera just invested $100m in. investor.coursera.com/news/news-de...
Our strategic investment in LearnVector has the potential to be a force multiplier for our growth. Andrew's unmatched AI expertise pairs his agentic AI with our platform and assets that turn learning into validated mastery — a clear competitive advantage that we believe can accelerate our business and expand the impact we deliver for individuals and enterprises around the world.
— Greg Hart, CEO, Coursera 

Source https://learnvector.ai/ Building on the broader reach we’ve gained through Udemy, this investment reflects our conviction that AI can help grow the market itself by making learning more continuous, more personal, and more embedded in people’s daily lives. In other words, we’re focused on creating a much bigger opportunity for learning overall.

As LearnVector develops new AI-native learning experiences, we’re exploring powerful ways to combine those advances with Coursera’s unique strengths: trusted content, insights from more than 300 million learners, and one of the world’s largest ecosystems of university and industry partners.

A question I ask myself all the time, how complex should I make things be? "Oversimplified models can, of course, give misleading results, but excessively detailed models can obscure interesting results beneath inessential and unconstrained complexity." Dayan and Abbott (2001)

In my opinion, there is an innate ancient evolutionary drive to use technologies that brings comfort to save energy. However, not every evolutionary bias is useful now a days and active interventions are needed to ensure the continuation of our civilisation. Too grand, I know 😄

Memory accessibility might be dependent on the current brain state. Think of Hopfield network, where the input is the current stimulus + brain state. It is not that you needed time, it is that on an X day the current brain state facilitated the access of Y memories in my opinion.

In my opinion, the problem of consciousness is that some people can’t accept that chemicals and electric charges can be the reason for their experiences and feelings. The transformation from physicality to subjective experience might not be ever quantified, but nonetheless is true.

Maybe I don’t get it, but I am not 100% on comparing LLMs simulating consciousness to computers simulating a hurricane. Simulations are abstractions with certain assumptions. However, if a system can emulate and predict every behaviour of another system, aren’t they functionally equivalent?

I see papers write "we use Euler" for integration in dynamical systems. Euler is inherently unstable for stable points that are center. It would be great to stress if one is using pure Euler or other modifications like Euler-Cromer or Verlet. I think this is an important detail in a papers methods.
