With Google removing their Responsible AI Principles, they no longer state that they will *not* engage in "Technologies whose purpose contravenes widely accepted principles of international law and human rights".
Concerns about surveillance and injury are also erased.

Folks are mostly missing the forest for the trees re: the recent Meta announcement. Specifically, the focus on the move from fact checking to community notes. There two different changes that are a much bigger deal that have received less focus. 🧵 1/11

I got Claude to condense github.com/mattjj/autod... to a single file to make it more readable: gist.github.com/gngdb/a6bdf4...
It's the same design as the core Jax autograd engine as far as I know.

Our poster is up in the compression workshop for Esha Singh's paper on bounds for scaling sparsity. We investigated better ways to compare sparsity inducing regularizers by grounding to compute efficient dense models. openreview.net/forum?id=qOn...

Sparsity in deep neural networks promises two improvements in computational efficiency, fewer FLOPs spent both to train the network and to perform inference. We find that both may be quantified...

How do a neural network's final parameters depend on its initial ones?

In this new paper, we answer this question by analyzing the training Jacobian, the matrix of derivatives of the final parameters with respect to the initial parameters.

I would put this even more strongly: open source AI is probably our only realistic chance to avoid a terrifying increase in concentration of power. I do not want to live in a world where the people with all the money also have all the intellectual power.
The most realistic reason to be pro open source AI is to reduce concentration of power.

A feature/bug of BlueSky is that you can back-date posts. People are using this to repost their tweets.
If you search for posts from the 1st century, there are jokes about the resurrection of Jesus. And, perhaps even funnier, some posts dated 24-11-20 instead of 2024-11-20.

One of the hardest,and most meaningful, projects I do in my job is monitor the epidemic of fatal violence against the trans and gender-expansive community.

Today, on Transgender Day of Remembrance (#TDOR), we honor those we’ve lost over the last year.

In summary, Ford's bike lane removals will, according to a new City Hall report:

- Cost $75 million in direct costs and sunk costs.
- Make traffic much, much worse for at least nine months during construction to remove lanes
- Have minimal long-term impact on car travel times.

We're cooked. The economy's cooked. The planet is really cooked.

But trans people are especially cooked, here in the U.S.

Because no one's coming to save us:

RIP Lynn Conway, chip design pioneer and transgender-rights advocate

From wiki: IBM fired Conway in 1968 after she revealed her intention to transition. IBM apologized in 2020 (!).

To do machine learning research it's important to have a degree in maths so you can read the math in most papers, a degree in computer science so you can write replicable code and a degree in physics so you can talk to all the physicists here. Luckily, getting them will leave no time for research.

When Karpathy said he can't watch any movie more than 20 years old he was actually using Cunningham's rule to get movie recommendations, obviously.

The fact about polar bear fur being technically transparent is dumb if you think that means you shouldn't say the fur is white but much more interesting if you know that the same transparent structure makes the bears mostly invisible in IR, so night vision would be useless.
