@wjscheirer.bsky.social Can the conferences offer targeted subsidies to some attendees (e.g., students) to book rooms in conference hotels? Assuming attrition fees scale with number of unbooked rooms, that seems a better use of funds than simply paying them to the hotels and may be a win-win.

We also present a solution to the problem, showing how we can efficiently estimate 2nd order information and largely mitigate the poor conditioning, opening the door for efficient, SGD-based high resolution cryo-EM methods.
marcusabrubaker.bsky.social
We show the numerical conditioning of cryo-EM reconstruction is increasingly poor at high resolution such that SGD has no real hope of resolving high resolution structures.
marcusabrubaker.bsky.social
Ever wonder why SGD, which works so well for ab initio cryo-EM, never seems to get to high resolution on its own? Well, we have the answer: conditioning!

Calling all PhD students in vision/ML interested in working with a great team (+me!) at GDM doing cutting edge research in 3D computer vision and generative models!
marcusabrubaker.bsky.social
Definitely. None of those things automatically go away just because someone gives you a degree!

A very similar argument (start with a basic set of requirements/axioms) can be made to show that probabilities are basically the only logically consistent calculus of uncertainty, see en.wikipedia.org/wiki/Cox%27s...

Anne Gagneux, Ségolène Martin, @quentinbertrand.bsky.social Remi Emonet and I wrote a tutorial blog post on flow matching: dl.heeere.com/conditional-... with lots of illustrations and intuition!

We got this idea after their cool work on improving Plug and Play with FM: arxiv.org/abs/2410.02423

For those who missed this post on the-network-that-is-not-to-be-named, I made public my "secrets" for writing a good CVPR paper (or any scientific paper). I've compiled these tips of many years. It's long but hopefully it helps people write better papers. perceiving-systems.blog/en/post/writ...

6 years ago, in the days of GAN art, I wrote an article called "Can Computers Create Art?", arguing that computers should not be considered artists, regardless of how good image generation gets. People sometimes ask if my views have changed. I say, 1/🧵

Here's my the talk for the #SIGGRAPH 2024 Computer Graphics Achievement award, about my experiences in painting, computer graphics and the science of art. And how so much art and research are unplanned and unpredictable.
