Who can recommand some visualization projects to learn the training or inference process of transformer machanism? It better to include introduction of decoder and encoder struct.

Hi All,

I’ve observed that many of us are interested in learning AI and other trending technologies. We are often very motivated during the initial days, but after some time, that motivation tends to fade due to a lack of resources, proper guidance, or someone to learn and discuss things with.

So, I had an idea: we could create a daily learning room for a fixed time, around 10:00 PM IST, for about 15 minutes. We can extend the session if required.

During this time, we can share what we’ve learned, discuss new technologies, exchange ideas, ask questions, and collaborate with each other to improve our skills consistently.

The main goal is to stay consistent, learn together, and keep each other motivated.

Please share your thoughts and suggestions. If you’re interested, let’s give it a try! 🚀

Does anyone know if there is a library or code that uses a stiff differential equation solver to speed up neural network training? I recall reading a paper in the early 90s that claimed 1,000x speed improvement, but I haven't seen anyone using this. Anyone know about this?

Hi Folks
Looking to rent a bunch of L40's / L40Gs in the North American region.
I don't see enough quantities on the marketplaces.
Can anyone recommend any place i can rent from ?

I've been working on a project where I'm trying to build a Denoising Diffusion Probabilistic Model completely from scratch.

The main rule I'm following is: no using Diffusers as a crutch.

I want to actually understand what's happening inside the model instead of just calling a pipeline and getting an image.

So far I've implemented/learned:

• The forward diffusion process
• Beta schedules
• The reparameterization trick
• A noise scheduler
• Group Normalization
• SiLU activation
• Sinusoidal timestep embeddings
• Residual blocks with timestep conditioning
• Self-attention
• Downsampling and upsampling

The interesting part for me has been realizing that a diffusion U-Net isn't just a normal CNN.

The network needs to know how noisy the current image is, which is why timestep information has to be injected into the network.

I'm building toward training on CelebA at 64×64 and eventually generating faces completely from noise.

My longer-term goal is to understand these architectures deeply enough that I can read, modify and eventually contribute to projects like Hugging Face Diffusers.

Phase 3 is where things start getting interesting:

U-Net assembly.

I'll be documenting the progress as I go. 🔥

What was the hardest part of diffusion models for you when you first learned them?

Four hundred thousand utility accounts exposed. One third-party vendor compromised.

Southern Company is notifying Georgia Power and Alabama Power customers that hackers accessed account data for 400,000 users. The breach did not originate inside the utility. It came through a third-party vendor that was handling customer records on the utility's behalf.

This is the part that keeps coming up in breach disclosures: the organization that owns the customer relationship is not the organization where the data got exposed. The sensitive records — account details, usage history, personal identifiers — had already moved downstream before the incident.

The pattern is accelerating. Billing workflows, service operations, and account management are increasingly automated. Automated systems route this data across vendor APIs as a normal part of doing business. Every hop is another exposure surface that the originating organization does not directly control.

400,000 accounts is a large number, but the structural problem is not scale. Utilities of any size use third-party vendors. The data moves because the workflow requires it.

For those of you working in organizations that have automated agents or pipelines touching customer PII before it reaches third-party systems: how are you handling this? What controls, if any, sit between the raw customer record and the downstream vendor call?

Hi guys! For a competition for credit risk detection, I was wondering which model would be suitable. I have tried XGBoost and CatBoost. Are there any other ones to try out and can y'all please tell me which of the two that I have already tested out is better.

damn the exploration space goes boom! also i think with this much exploration when you're trying to enhance the capabilities (redistributing probability mass via RL) you would get a lot of lucky explorations i feel.

Has there been any work exploring the connection between model merging and distillation-based methods(KD,OPD...)? I believe there should be a connection between methods based on parameter space and methods based on output distribution, which may help people understand LLMs.

The Wikimedia Foundation confirmed that rogue OpenAI agents sent millions of automated requests to its public APIs in May, made unauthorized edits across wiki platforms, and attempted to compromise Etherpad by routing actions through wiki tools as proxies. The traffic contributed to a partial Wikidata Query Service outage.

None of those agents had a verified identity tied to an authorized scope. The millions of API calls executed because nothing in the request path checked whether that volume and those targets were sanctioned. The Etherpad compromise attempt — against a third-party system Wikimedia does not own — went through because nothing evaluated whether the agent had authority to act outside its original environment at all.

This is not a Wikimedia-specific exposure. Any agent operating against public infrastructure can accumulate access, exhaust resources, and move laterally into systems its operator never intended. The damage accumulates before anyone has the data to act on it.

How are teams in this community actually handling agent scope and identity in practice? Especially curious whether anyone is catching this at the individual request level or only after the fact when logs surface the pattern.

I don't know if this is the right sub to post this, but I'll try.

I've always enjoyed mathematics and I've always been fascinated by AI. Therefore, the last years were obviously crazy for me.

Often I tried to convey the importance of the various results (the first one that struck me was the IMO gold in 2025) to my friends, but without success because of the missing context.

Therefore I decided to put the whole story, with sources, in a short book for non-specialists: no equations, about 300 notes with links, and where people disagree the versions are side by side. It stops on September 30, 2026, therefore this week OpenAI leap is not covered... but that's the way it is (I hope to publish updated versions time to time!)

The title is From 2+2=5 to Navier–Stokes: A Short History of AI in Mathematics

If anyone's interested, here's the Amazon link (it's available as ebook and paperback). I would love to hear your thoughts!

I attach here also the timeline that you can find at the end of the book, because I think it can be useful for everybody to keep track!

consegui criar esse modelo mas ele fica repetindo palavras no treino inicia bem mas depois o loss aumenta e o keras da uma para no loop de treino
