🔥 #LeAVJEPA: A simple recipe for self-supervised learning from sound and vision 🔥 One shared encoder, trained without class labels. Dropping a modality makes audio & video learn a common representation. 🧵

6/ Smol-GS is not just smaller. It keeps rendering fast, preserves high visual quality, and avoids the structural overhead of anchors. 🥇On the 3DGS.zip benchmark, it currently gives the best size–quality trade-off: w-m.github.io/3dgs-compres...

5/ Tiny MLPs decode each splat into what the renderer needs: color, opacity, shape, rotation, and view-dependent effects. The features and scale controllers are quantized and entropy-coded. The result is a compact neural splat representation without anchor-offset bookkeeping.

4/ In Smol-GS, each splat has a compact learned feature vector. Geometry stays explicit, but coordinates are stored with an occupancy-octree. The same octree also gives a locality-aware positional encoding. In short: explicit geometry + learned local appearance.

3/ Most strong 3DGS compression methods are anchor-based: Store shared anchors, use local offsets, and decode splats around them. That works well and has dominated recent benchmarks. But Smol-GS takes a different approach.

3D Gaussian splats are amazing--until you realise how much storage space they need. Smol-GS makes #3DGS actually small: explicit splats, tiny learned features w/ positional awareness, octree-coded geometry, and fast rendering. 🥇Now leading the 3DGS.zip benchmark.

1/ 🔥 New paper: Differentiable Vector Quantization (DiVeQ) 🔥 Vector quantization (VQ) is a core tool in modern AI. It connects continuous data like images and audio to discrete tokens used by transformers. It underpins compression, generation, and multimodal modelling.

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.

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]

There is still time to submit your papers to our #CVPR2025 workshop on Uncertainty Quantification for Computer Vision, which is part of the workshop lineup at the IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) in Nashville, Tennessee.

I also stumbled upon the “Classical Mechanics Lab” (in the picture), and physics labs sure are different than I thought.

This week I have been teaching ML outside my own academic bubble. 🫧 I have been giving a crash course as part of the #Nordita Winter School on "Physics of Machine Learning & Machine Learning for Physics“ in Stockholm. Great interaction with young physicists and new avenues for applying ML. ✨
