How could online learning apps adapt to learners and improve over time? Even if you're not a machine learning expert, Hanqi Zhou's blog post on our last ICLR paper explains new approaches in simple terms (joint work with 🐘 Álvaro Tejero-Cantero @[email protected] and Charley Wu (@thecharleywu.bsky.social), supported by Theresa Authaler).

I am super hyped and happy with our recent paper on a ✨VampPrior 2.0✨: Hierarchical VAE with a diffusion-based VampPrior 🦇 We got SOTA VAE results! Kudos to Anna Kuzina, this TMLR paper is the last chapter in her PhD thesis 🤩 📃 tinyurl.com/22rvzc4f 💻 tinyurl.com/3ddrbfcj

How to find all fixed points in piece-wise linear recurrent neural networks (RNNs)? A short thread 🧵 In RNNs with N units with ReLU(x-b) activations the phase space is partioned in 2^N regions by hyperplanes at x=b 1/7

Latent Diffusion for Neural Spiking Data -- a flexible generative model for realistic neural recordings co-led with A Schulz! This was a very fun and intense project, and my first (and hopefully not the last) foray into #neuro! Check out the thread - lots of pretty plots

𝟏/ 🚨Attention NeurIPS attendees! 🚨 Isotropic weight space priors are sabotaging your Laplace approximation to your neural network’s posterior, and we’ve got the fix. Curious? Read on 🧵

I'm extremely disappointed with the organization of the upcoming German election. Voting is a fundamental right, yet my ballot letter arrived too late in Toronto—now the fastest! delivery won't get it there by Monday, after the election. Unacceptable. Die Bundeswahlleiterin German Consulate TO

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