🔥 ACE-G, the next evolutionary step of ACE at #ICCV2025 🔥
We disentangle coordinate regression and latent map representation which lets us pre-train the regressor to generalize from mapping data to difficult query images.

Wrt to RoPE: People are applying it wrongly for multi-view, if you do it VGGT style you will mix the positions of all the images. You should do it independently (i.e. no rope between images).
