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.

2026 Conference

Arno Solin @arnosolin.bsky.social · Aug 12

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]

Arno Solin @arnosolin.bsky.social · Aug 12

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]

📣 Please share: We invite submissions to the 29th International Conference on Artificial Intelligence and Statistics (#AISTATS 2026) and welcome paper submissions at the intersection of AI, machine learning, statistics, and related areas. [1/3]

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.

DeSplat: Decomposed Gaussian Splatting for Distractor-Free Rendering

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

Arno Solin @arnosolin.bsky.social · Jun 9

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

Arno Solin @arnosolin.bsky.social · Jun 9

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.

Our method addresses the eminent question of probabilistic modelling in quantized large-scale ML models. See the workshop paper below. [3/3]

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]

Arno Solin @arnosolin.bsky.social · Apr 29

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]

Arno Solin @arnosolin.bsky.social · Apr 27

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.
