I'm excited to share that our work on #deeplearning based shape modeling is finally out in #ieee.

🧵 for info about Data, Benchmarks, and Models!

Is this less of a trick if the goal is to see the SMD on elite athletes? It’s only biasing it/misleading if we are interpreting the effect size for the population of all people?

This ☝🏽 💯

If 🇨🇦 created a thriving research environment by investing in tri-council & ditching the PJT focused approach that kills investment in long term programs - we would ATTRACT international talent vs bribing them to move here; to only leave later when they see there’s no sustainable funding!

I can't* fathom why the top picture, and not the bottom picture, is the standard diagram for an autoencoder.

The whole idea of an autoencoder is that you complete a round trip and seek cycle consistency—why lay out the network linearly?

“Everyone knows” what an autoencoder is… but there's an important complementary picture missing from most introductory material.

In short: we emphasize how autoencoders are implemented—but not always what they represent (and some of the implications of that representation).🧵

We are starting to see some nuanced discussions of what it means to work with advanced AI in its current state

In this case, GPT-5 Pro was able to do novel math, but only when guided by a math professor (though the paper also noted the speed of advance since GPT-4)

The reflection is worth reading.

Google Gemini doesn’t appear to be doing too well:

‘"I am a disgrace to this planet. I am a disgrace to this universe. I am a disgrace to all universes . . . I am a disgrace to all possible and impossible universes and all that is not a universe," the bot continued.’

Google says it's working on a fix for Gemini's self-loathing 'I am a failure' comments

Google Gemini users said the bot is sharing self-loathing messages while attempting to solve tasks, including "I am a disgrace to this universe."

Methods like NeRF and Gaussian Splats model the world as radioactive fog, rendered using alpha blending. This produces great results.. but are volumes the only way to get there?🤔 Our new SIGGRAPH'25 paper directly reconstructs surfaces without heuristics or regularizers.

Rest in peace, boss. @beierlab.bsky.social -- your stoic and positive support helped me in too many ways to count over the years.

Cancer update. A bit darker than usual. Cancer has advanced and it looks like I only have a few months left. Took me a few days to get used to this new timeline. Time to start wrapping things up at home and at the lab. Thankfully there is little pain and I am relatively functional.

I love this type of approach - for imaging, biomechanics, or other domains…

Take high quality dense data, use physics simulators to generate synthetic sparse data, then train a model to recon dense data from sparse measurements.

Lots of potential pitfalls, but the concept is immensely powerful.

White text on white background instructing LLMs to give positive reviews is apparently now common enough to show up in searches for boilerplate text.

I’m torn on this.

I feel like it is valuable to be honest in the data and to improve it if things change/update.

But it just seems like a nightmare to keep up on the literature when not only is there a new paper, but the one you’ve read changed.

Are there useful or interesting ways to use LLMs other than prompting them? I feel like compressing all the text in the world via a hierarchically structured statistical model is probably useful, but that we're using it in a way that is unlikely to do what we'd hope.

Since LLMs came out I’ve thought they are the perfect tool for systematic reviews. This is an excellent use case.

Ethan Mollick @emollick.bsky.social · Jun 14

👀This is impressive: Using an autonomous agent based on o3-mini and GPT-4.1, a team from Harvard, MIT & other institutions reproduced and updated an entire issue of Cochrane Reviews in two days… saving 12 person-years of work.

The AI reviews captured more papers & were more accurate than humans.

Are you interested in muscle #biomechanics and looking for #postdoc opportunities?

If you have skills in (statistical) shape modelling, advanced data analyses or 3D imaging/model reconstructions, get in touch with me!

I will be at #SEB2025 (Antwerp), #CNB2025 (Helsinki), and #ISB2025 (Stockholm).

You can never cover everything - totally fair.

Now makes me wonder about this approach for fitting a generative model to a new example. Eg optimizing latent vector to best recon new surface.
