Inventors of flow matching have released a comprehensive guide going over the math & code of flow matching!

Also covers variants like non-Euclidean & discrete flow matching.

A PyTorch library is also released with this guide!

This looks like a very good read! 🔥

Jane Street, a quant trading firm has a very good YouTube channel. For comparison, DeepSeek is also a quant trading firm.

They recently published a video on "Building Machine Learning Systems for a Trillion Trillion Floating Point Operations".

A dataset of 1 million or 2 million Bluesky posts is completely irrelevant to training large language models.

The primary usecase for the datasets that people are losing their shit over isn't ChatGPT, it's social science research and developing systems that improve Bluesky.
Did you know that 99% of email today is spam? Your inbox isn’t 99% spam because AI is used to filter it.

The same 99% will happen here too, but if AI researchers continue to get perma-banned for making available the datasets needed to filter it, it’s going to make this platform unusable.

In fact, statistical malpractice is the main driver of progress in machine learning. At some point, we need to come to terms with this.

There seems to be some renewed interest in making this work in the ML/AI space, so I'm here as well 👋

Here's my latest blog post for good measure, about how diffusion models of images perform autoregression in frequency space: sander.ai/2024/09/02/s...

When I write more, I'll share here as well!
Diffusion is spectral autoregression
A deep dive into spectral analysis of diffusion models of images, revealing how they implicitly perform a form of autoregression in the frequency domain.

Quick thread in response to a question on token packing practices when pretraining LLMs!
Yes! Token packing has been the standard since RoBERTa. Excerpt below!

The intuition is that the model quickly learns to not attend across [SEP] boundaries and packing avoids "wasting" compute on padding tokens required to make the variable batch size consistent.

Thinking how much Google struggled to get TPUs to work well makes me skeptical that Nvidia is in any danger of losing dominance, at least for now.
Will Nvidia continue to dominate the AI chip market? Yes and no.

- Yes, Nvidia is likely to maintain dominance in the market for training AI models.
- No, another company (or companies) will take the lead in the market for AI model inference, which is an exponentially larger market.

I try to stay up to date with Gen AI videos, but you can do camera control now? Seriously?

Runway introduces advanced camera control for Gen-3 Alpha Turbo. Choose both the direction and intensity of how you move through your scenes for even more intention in every shot.

#Tokenization is undeniably a key player in the success story of #LLMs but we poorly understand why.
I want to highlight progress we made in understanding the role of tokenization, developing the core incidents and mitigating its problems. 🧵👇
