Diffusion modeling from a Bayesian inference perspective: instead of denoising a sample, we infer it from repeated noisy measurements. Our perspective generalizes Bayesian Flow Networks and achieves better sample quality in fewer steps than BFNs. arxiv.org/abs/2502.07580 github.com/martenlienen...
BSI generates a picture of a bunny through repeated prediction and inferenceVisualization of the four parts of each BSI step:

1. We have a current belief about the sample
2. From this, predict what sample "hides" behind our belief
3. Take a noisy measurement from that prediction
4. Form the posterior belief about the sample

We introduce BayesVLM, a training-free post-hoc Bayesian method for uncertainty estimation in pretrained VLMs. BayesVLM yields interpretable, well-calibrated uncertainty with virtually no inference overhead.

SDPO enables RL agents to learn from rich feedback (i.e., not only whether an attempt failed, but why it failed, such as error messages). Even without such rich feedback, SDPO can reflect on past attempts and outperform GRPO. SDPO also accelerates solution discovery at test time!

Training LLMs with verifiable rewards uses 1bit signal per generated response. This hides why the model failed. Today, we introduce a simple algorithm that enables the model to learn from any rich feedback! And then turns it into dense supervision. (1/n)

It's really hard to tell nowadays what is a made-up joke and what is reality.

Unfortunately, our submission to #NeurIPS didn’t go through with (5,4,4,3). But because I think it’s an excellent paper, I decided to share it anyway. We show how to efficiently apply Bayesian learning in VLMs, improve calibration, and do active learning. Cool stuff! 📝 arxiv.org/abs/2412.06014

I'm very excited to share notes on Probabilistic AI that I have been writing with @arkrause.bsky.social 🥳 arxiv.org/pdf/2502.05244 These notes aim to give a graduate-level introduction to probabilistic ML + sequential decision-making. I'm super glad to be able to share them with all of you now!
