So exciting to see everyone here. A brief self-intro for others:

I am currently a PhD student with @florianjug.bsky.social. My work involves the application of AI in bioimage analysis. I am interested in the application of #GenAI to solve inverse problems with #DiffusionModels #FlowMatching #VAEs.

“We may not win every battle, but we will win the war.” --- Such an appropriate characterization for posterior samplers. Each posterior sample fights its own battle against noise and degradation; some win, some lose. But the MMSE estimate wins the war 😉.

Diffusion Transformers with Representation Autoencoders by Boyang Zheng, et al (arxiv.org/abs/2510.116...)

Unexpected result: swapping the SD-VAE for a pretrained visual encoder improves FID, challenging the idea that encoders' information compression is not suited for generative modeling!

New episode in this line of work from @giannisdaras.bsky.social et al. on training diffusion models with mostly bad/low-quality/corrupted data (+few high-quality samples). This time for proteins!

New paper on the generalization of Flow Matching www.arxiv.org/abs/2506.03719

🤯 Why does flow matching generalize? Did you know that the flow matching target you're trying to learn *can only generate training points*?

Kullback–Leibler (KL) divergence is a cornerstone of machine learning.

We use it everywhere, from training classifiers and distilling knowledge from models, to learning generative models and aligning LLMs.

BUT, what does it mean, and how do we (actually) compute it?

Always found the connection between rectified flows and optimal transport a bit confusing. Glad to see some clarity. TL;DR: Rectified flows ≠ optimal transport. arxiv.org/abs/2505.19712

On the Relation between Rectified Flows and Optimal Transport

This paper investigates the connections between rectified flows, flow matching, and optimal transport. Flow matching is a recent approach to learning generative models by estimating velocity fields th...

I'm not sure EBM will beat flow-matching/diffusion models, but this article is very refreshing.

New Feature in DeepInverse (deepinv.github.io):

🚀 Custom Diffusion Solver Design
DeepInverse now simplifies the process with:

✔ Standard SDEs (VP, VE, etc.)
✔ Pretrained denoisers for multiple noise levels
✔ ODE/SDE solvers (Euler, Heun)
✔ Noisy data fidelity terms for guidance

Really interesting paper on per-frequency control in diffusion models: arxiv.org/abs/2505.112.... They tackle the frequency degradation rate imbalance of the forward process by enforcing Equal SNR across Fourier components. Finally, someone’s taking @sedielem.bsky.social blogs to heart 👀🔥

Here's the third and final part of Slater Stich's "History of diffusion" interview series!

The other two interviewees' research played a pivotal role in the rise of diffusion models, whereas I just like to yap about them 😬 this was a wonderful opportunity to do exactly that!
