Yes. The easiest way to find it will be on the website virtual.aistats.org We are in the process of adding material there and will add a link.

We will go public with it as soon as everything is set up with the venue.

I'm thrilled to be Program Chairing AISTATS 2026 together with Aaditya Ramdas. AISTATS has a special feel to it, and it has been described by many colleagues as their "favourite conference". We aim to preserve that spirit while introducing some fresh elements for 2026. [3/3]

Accepted papers will be presented in person in Morocco, May 2–5, 2026. The full Call for Papers is available here: virtual.aistats.org/Conferences/... [2/3]

Remember that computers use bitstrings to represent numbers? We exploit this in our recent @auai.org paper and introduce #BitVI.

#BitVI directly learns an approximation in the space of bitstring representations, thus, capturing complex distributions under varying numerical precision regimes.
BitVI on 1D Gaussian mixture models.

Qualitative visualization of static distractor elements achieved by our model, DeSplat. [3/n]

Compared to Splatfacto we model and can ignore distractors to improve 3DGS reconstruction quality. [2/n]

Real-world #3DGS scenes are messy—occluders, moving objects, and clutter often ruin reconstruction. This #CVPR2025 paper presents DeSplat, which separates static scene content from distractors, all without requiring external semantic models. [1/n]

I’m visiting the Isaac Newton Institute for Mathematical Sciences in Cambridge this week.

I’m giving an invited talk in the ”Calibrating prediction uncertainty : statistics and machine learning perspectives” workshop on Thursday.

We introduce BitVI, a novel approach for variational inference with discrete bitstring representations of continuous parameters. We use a deterministic probabilistic circuit structure to model the distribution over bitstrings, allowing for exact and efficient probabilistic inference. [2/3]

Have you thought that in computer memory model weights are given in terms of discrete values in any case. Thus, why not do probabilistic inference on the discrete (quantized) parameters. @trappmartin.bsky.social is presenting our work at #AABI2025 today. [1/3]

We show that externalising reasoning as a DAG at test time leads to more accurate, efficient multi-hop retrieval – and integrates seamlessly with RAG systems like Self-RAG.

This work was born out of Prakhar's internship with Microsoft Research (\w Sukruta Prakash Midigeshi, Gaurav Sinha, Arno Solin, Nagarajan Natarajan, and Amit Sharma).

Alignment is Key for Applying Diffusion Models to Retrosynthesis
Retrosynthesis, the task of identifying precursors for a given molecule, can be naturally framed as a conditional graph generation task. Diffusion models are a particularly promising modelling approac...
