Here's my 3DV talk, in chapters: 1) Intro / NeRF boilerplate. 2) Recent reconstruction work. 3) Recent generative work. 4) Radiance fields as a field. 5) Why generative video has bitter-lessoned 3D. 6) Why generative video hasn't bitter-lessoned 3D. 5 & 6 are my favorites.

Flow matching produces smooth, deterministic trajectories. In contrast, the sampling process of a diffusion model is chaotic, resembling the random motion of gas particles.

💥 Forget slow autoregression and skip rigid full-sequence denoising! Nexus is a next-gen predictive pipeline for realistic, safety-critical driving scene generation. What’s new? ✅ Decoupled diffusion → fast updates, goal-driven control ✅ Noise-masking training → inject

When at #CVPR2025 a major challenge is how to split yourself among super amazing workshops. I'm afraid to announce you that with our workshop on "Embodied Intelligence for Autonomous Systems on the Horizon" we will make this choice even harder: opendrivelab.com/cvpr2025/works… #cvpr2025

Thanks for sharing! I will host the workshop for a whole day and welcome anyone who is struggling with current embodied AI trend! We want to hear the opposite opinions from vision and robotics people on the topic of autonomy.

Today we're excited to share a glimpse of what we're building at Generalist. As a first step towards our mission of making general-purpose robots a reality, we're pushing the frontiers of what end-to-end AI models can achieve in the real world. Here's a preview of our early

Wrapped up Stanford CS336 (Language Models from Scratch), taught with an amazing team Tatsunori Hashimoto Marcel Rød Neil Band Rohith Kuditipudi. Researchers are becoming detached from the technical details of how LMs work. In CS336, we try to fix that by having students build everything:

Current robot policies often face a tradeoff: they're either precise (but brittle) or generalizable (but imprecise). We present ViTaL, a framework that lets robots generalize precise, contact-rich manipulation skills across unseen environments with millimeter-level precision. 🧵
