What is the right metric to measure performance in structured 3D reconstruction?

🎬 Just posted the video for our @iccv.bsky.social #ICCV2025 highlight paper! 🎉

Explaining Human Preferences via Metrics for Structured 3D Reconstruction

tl;dr: we asked 3D modelers to rank wireframe reconstructions & compared it to ranking by metrics. Observations🧵

hey @cloneofsimo.bsky.social (or anyone else) did you ever try LoRA+ style LR split between down/up LoRA projection matrices on diffusion models?
LoRA+: Efficient Low Rank Adaptation of Large Models Soufiane Hayou, Nikhil Ghosh, Bin Yu In this paper, we show that Low Rank Adaptation (LoRA) as originally introduced in Hu et al. (2021) leads to suboptimal finetuning of models with large width (embedding dimension). This is due to the fact that adapter matrices A and B in LoRA are updated with the same learning rate. Using scaling arguments for large width networks, we demonstrate that using the same learning rate for A and B does not allow efficient feature learning. We then show that this suboptimality of LoRA can be corrected simply by setting different learning rates for the LoRA adapter matrices A and B with a well-chosen ratio. We call this proposed algorithm LoRA+. In our extensive experiments, LoRA+ improves performance (1-2 % improvements) and finetuning speed (up to ∼ 2X SpeedUp), at the same computational cost as LoRA.

Lots of progress in mech interp (MI) lately! But how can we measure when new mech interp methods yield real improvements over prior work?

what is the best intro I can send people who suddenly want to know "what is AI?" and "what is a transformer based model?" but arent really going to invest tons of time and maybe dont have any math background?

my default is 3b1b, but does anyone have another suggestion?

lol 4o just decided to throw this rocket emoji into a normal technical conversation for no apparent reason

who's overly excited discord / slack is responsible for this?
If you'd like to see a concrete example of REDACTED could be implemented or compared to REDACTED (e.g., in PyTorch), let me know! I can walk you through code or provide further insights. 🚀

Andrej Karpathy @karpathy Al video generation today. When I was back in school, the story of the field of computer graphics (and physically based rendering etc.) was that we will carefully study and model all the object/scene geometry, physics rendering etc., and after 1000 PhDs and 50 SIGGRAPHs get results like this. That a Transformers can shortcut all of that at this high of fidelity by training on a dataset of videos...
