Great paper by my students @TimZXiao and @johanneszenn and collaborators that applies ideas from Monte Carlo sampling to (black-box) LLM execution to turn LLMs into better calibrated stochastic samplers.

✨ New paper: Flipping Against All Odds We found that large language models (LLMs) can describe probabilities—but fail to sample from them faithfully. Yes, even flipping a fair coin is hard. 🪙 🧵 Here’s what we learned—and how we fixed it. 🔗arxiv.org/abs/2506.09998 1/

How could online learning apps adapt to learners and improve over time? Even if you're not a machine learning expert, @hanqizh's blog post on our last ICLR paper explains new approaches in simple terms (joint work with @alvorithm and @TheCharleyWu, supported by @TheresaAuthaler).

Come join us at poster 2610 today from 11:30 am to 1 pm at #ICML2024
Differentiable annealed importance sampling (DAIS) minimizes the Jensen-Shannon divergence between its initial and target distribution! Check out our work (arxiv.org/abs/2405.14840) with @robamler and meet us at the poster at ICML in Hall C 4-9 #2610 in the morning session today!

🤔What about using an LLM as a function approximator for f(x; θ) where the parameters θ are natural language? 🤔Can we learn θ just like in machine learning (ML) where θ are numerical values? ✨Check out Verbalized ML, where data and models both operate in natural language! 🤩

Did you know that the training/test set split of the SVHN data set is biased, making SVHN unsuitable for evaluating generative models? Learn more from my students @TimZXiao and @johanneszenn at the DistShift workshop at #NeurIPS2023 tomorrow (10.30 am, room R06-R09).

🚨The training and test set of the Street View House Numbers (SVHN) dataset are NOT from the same distribution!🚨 Join us at the #NeurIPS2023 workshop on DistShift this Friday (10:30 am, room R06-R09) to find out more! arxiv.org/abs/2312.02168 w/ @johanneszenn @robamler

Training variational autoencoders on samples from a diffusion model essentially eliminates their known tendency to overfit the encoder without sacrificing model performance. Congrats to my PhD students @TimZXiao and @johanneszenn on their latest preprint! arxiv.org/abs/2310.19653

If you're at ICLR, join my student @johanneszenn at the Tiny Paper poster session today from 1.15 to 3.15 pm in room MH4. You'll be surprised how many insights can fit in a 2-page paper! arxiv.org/abs/2304.14390

If you're in Kigali for ICLR this week, let's meet and chat over some drinks tomorrow at @TimZXiao's poster on rate/distortion theory of hierarchical VAEs. It's poster #106 in the MH rooms from 4:30 to 6:30. iclr.cc/virtual/2023/poster/…

There is no need for gradients due to resampling in Differentiable Sequential Monte Carlo Samplers! Check out our recent work (arxiv.org/abs/2304.14390) with @robamler and meet us at the poster on Friday!

My student @johanneszenn found a useful fact about differential sequential Monte Carlo samplers: you can ignore any gradients due to resampling because they vanish in expectation. Check out his accepted ICLR DEI paper and meet us at the poster on Friday. arxiv.org/abs/2304.14390

We just got the green light to hold another workshop on machine-learning-based data compression—this time at ICML. I'm very excited! Stay tuned for details and for the call for papers.
🎉Exciting news! Our "Neural Compression" workshop proposal has been accepted at #ICML 2023! Join us to explore the latest research developments, including perceptual losses and more compute-efficient models! @BerivanISIK, @YiboYang, @_dsevero, @karen_ullrich, @robamler

Looking for the one VAE to rule them all? The bad news: it doesn't exist. The good news: our recently accepted ICLR 2023 paper shows how to optimally allocate information to each latent layer depending on your application: arxiv.org/abs/2302.04855 @TimZXiao @ml4science #ICLR2023

Ein super recherchierter Artikel! Ich bin begeistert, dass Zeitungen die gesellschaftliche Relevanz von IT-Themen erkennen. Schade nur, dass noch immer so viele Menschen ihrer Bürgerpflicht, sich über relevante Themen zu informieren, nicht nachkommen. 1/2 sueddeutsche.de/wirtschaft/s…

Informationsangebote gibt es viele (u.a. auch von @ml4science und @Cyber_Valley). Man muss sie aber auch nutzen, und dabei offen sein für Fakten und wissenschaftliche Erkenntnisse, und v.a. nicht auf Populisten mit nationalistischer/fremdenfeindlicher Rhetorik hereinfallen. 2/2
Wir können alles. Außer Hochdeutsch. Und ÖPNV. 🤦
