We’ve upgraded ShapeEmbed 🎉 ShapeEmbedLite decodes latent codes via an MLP to guarantee valid EDMs, making it lighter and ideal for small microscopy datasets or limited compute. Hear more at my BIC workshop talk or poster at #ICCV2025! Try it out at github.com/uhlmanngroup...

Looking forward to my talk at heidelberg.ai. I will touch on topics like #MapFreeReloc and #ACEZero, i.e. how to derive scene representations from very few (one!) or very many images.
We’re thrilled to welcome Eric Brachmann (@ericbrachmann.bsky.social), Senior Staff Scientist at Niantic Spatial, Inc. and a leading expert in visual relocalisation & pose estimation, to our heidelberg.ai / NCT Data Science Seminar on July 16th at 4 PM.

Unlocking a cycling achievement. Koenigstuhl was like another planet for me when I was doing my PhD @embl.org. My car (old communist Škoda 105L) had trouble getting there. By bike - unthinkable. 25 years later, I did it with a bio-bike! Via #EMBL from Rohrbach. Next challenge: #Steigerweg 🤠💪🚴♀️

Tweedie's formula is super important in diffusion models & is also one of the cornerstones of empirical Bayes methods.
Given how easy it is to derive, it's surprising how recently it was discovered ('50s). It was published a while later when Tweedie wrote Stein about it

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?
Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵
