🚀 Excited to share Sonata, our "3D-DINO" from @RealityLabs Research – a groundbreaking self-supervised model for 3D point clouds. It triples linear probing accuracy on ScanNet (21.8% → 72.5%)! See👇 for more details.

📢Sonata: Self-Supervised Learning of Reliable Point Representations📢 Meet Sonata, our"3D-DINO" pre-trained with Point Transformer V3, accepted at #CVPR2025! 🌍: xywu.me/sonata 📦: github.com/facebookresear… 🚀: github.com/Pointcept/Poin… 🔹Semantic-aware and spatial reasoning representations learned with no label; 🔹3x linear probing accuracy (from 21.8% to 72.5%) on ScanNet; 🔹2x data efficiency performance with only 1% of the data compared to previous approaches; 🔹As always, establish new SOTA results across indoor and outdoor 3D perception tasks. Our author team: @HengshuangZhao, @jstraub6, @rapideRobot, @ddetone, @NinjaDuncan, @TianweiS, @Christopher_Xie, @NanYang719.

I realize that the major feature of Adam and AdamW is decoupling the scale of loss from the step size applied to parameters, i.e. under constant 1-d gradient, the step size will be totally decided by the learning rate, which is the key difference to SGD

🔥 EFM3D: a new benchmark for 3D egocentric perception tasks The EFM3D benchmark measures progress on egocentric 3D reconstruction and 3D object detection to accelerate research on egocentric foundation models rooted in 3D space. A new model, EVL, establishes the first baseline.

Check out our latest research - Egocentric Voxel Lifting (EVL) on jointly conducting surface reconstruction and 3d object detection, on egocentric (projectaria.com) data!
Daniel DeTone@ddetone

What is the right benchmark for a 3D Egocentric Foundation model? We recently open-sourced a small, high quality egocentric benchmark consisting of 1) 3D surfaces 2) 3D objects. We released a simple 3D CNN baseline model called EVL: projectaria.com/research/efm3d/ Try to beat our model!

Rejected from CVPR (due, in part, to a lack of baseline results 🫠), our team is proud to present SceneScript, tomorrow, at ECCV (am session)!!! 1/
Edward Miller@TweetEdMiller

📢 Today, our team is excited to announce 𝑺𝒄𝒆𝒏𝒆𝑺𝒄𝒓𝒊𝒑𝒕: an end-to-end method for scene reconstruction from @RealityLabs Research, which enables AI agents to understand and describe 3D spaces. projectaria.com/scenescript /🧵

Aria Everyday Objects (AEO) is the first dataset released by ProjectAria which has high-quality human annotated 3d objects on real egocentric sequences. Check out our EFM3D project for more details! 📃Project page: projectaria.com/research/efm3D/ 💻GitHub code: github.com/facebookresear…
Daniel DeTone@ddetone

Interested in 3D object detection and egocentric vision? We open sourced a small yet challenging dataset called Aria Everyday Objects (AEO). We use it as one of the tasks for benchmarking a new class of Egocentric 3D Foundation Models we are working on: arxiv.org/abs/2406.10224

My favorite new equipment purchase for the lab – a travel crib to go in my office so my graduate student can bring her 9-month old little girl to work when necessary and I get to play with her while her mom gets some work done. Win-win!!

Move faster. Slowness anywhere justifies slowness everywhere. 2021 instead of 2022. This week instead of next week. Today instead of tomorrow. Moving fast compounds so much more than people realize.

Just did. Entries on Wikipedia are not perfectly accurate nor comprehensive. But it's such an important piece for our collective intelligence as human.
